  2. Nuclear methods in medical physics

    International Nuclear Information System (INIS)

    Jeraj, R.

    2003-01-01

    A common ground for both, reactor and medical physics is a demand for high accuracy of particle transport calculations. In reactor physics, safe operation of nuclear power plants has been asking for high accuracy of calculation methods. Similarly, dose calculation in radiation therapy for cancer has been requesting high accuracy of transport methods to ensure adequate dosimetry. Common to both problems has always been a compromise between achievable accuracy and available computer power leading into a variety of calculation methods developed over the decades. On the other hand, differences of subjects (nuclear reactor vs. humans) and radiation types (neutron/photon vs. photon/electron or ions) are calling for very field-specific approach. Nevertheless, it is not uncommon to see drift of researches from one field to another. Several examples from both fields will be given with the aim to compare the problems, indicating their similarities and discussing their differences. As examples of reactor physics applications, both deterministic and Monte Carlo calculations will be presented for flux distributions of the VENUS and TRIGA Mark II benchmark. These problems will be paralleled to medical physics applications in linear accelerator radiation field determination and dose distribution calculations. Applicability of the adjoint/forward transport will be discussed in the light of both transport problems. Boron neutron capture therapy (BNCT) as an example of the close collaboration between the fields will be presented. At last, several other examples from medical physics, which can and cannot find corresponding problems in reactor physics, will be discussed (e.g., beam optimisation in inverse treatment planning, imaging applications).

    The principle possibility of using computer program Univem MS for Mössbauer spectra fitting as a demonstration material at studying such disciplines as atomic and nuclear physics and numerical methods by students is shown in the article. This program is associated with nuclear-physical parameters such as isomer (or chemical) shift of nuclear energy level, interaction of nuclear quadrupole moment with electric field and of magnetic moment with surrounded magnetic field. The basic processing algorithm in such programs is the Least Square Method. The deviation of values of experimental points on spectra from the value of theoretical dependence is defined on concrete examples. This value is characterized in numerical methods as mean square deviation. The shape of theoretical lines in the program is defined by Gaussian and Lorentzian distributions. The visualization of the studied material on atomic and nuclear physics can be improved by similar programs of the Mössbauer spectroscopy, X-ray Fluorescence Analyzer or X-ray diffraction analysis.

Besides for expand an analyzed elements range and precision increase for quantitative characteristics of elementarily content of samples the X-ray florescent analysis method with isotope excitation (RFA) is using in the capacity complementary PIXE method. Modernization of proton beam transportation system at the heavy ion accelerator allows to develop a new analytical trend - combination of the proton micro-probe with PIXE analysis. In this case the information about examined sample elementary content is within size field ∼10 μm. The beam scanning by the surface is allowing to obtain the elements distribution by the two spatial coordinates connected with the surface.

    Full text: The activity of the Department of Nuclear Methods in the Solid State Physics is focused on experimental research in condensed matter physics. Thermal neutron scattering and Moessbauer effect are the main techniques mastered in the laboratory. Most of the studies aim at better understanding of properties and processes observed in modern materials. Some applied research and theoretical studies were also performed. Research activities of the Department in 2001 can be summarized as follows: Neutron scattering studies concerned the magnetic ordering in TbB 12 and TmIn 3 and some special features of magnetic excitations in antiferromagnetic γ-Mn-alloys. Some work was devoted to optimization of the neutron single crystal monochromators and polarizers grown in Crystal Growth Laboratory. Small angle scattering studies on the surfactant - water ternary system were performed in cooperation with JINR Dubna. Moessbauer effect investigations of dysprosium intermetallic compounds yielded the new data for Pauling-Slater curves. The same technique applied to perovskites and ferrocene adduct to fullerene helped to resolve their structure. X-ray topographic and diffractometric studies were performed on hydrogen implanted semiconductor surfaces employing the synchrotron radiation sources. The X-ray method was applied also to investigations of plasma spraying process and phase composition of ceramic oxide coatings. Large part of studies concerned the structure of biologically active, pharmacologically important organic complexes, supported by modeling of their electron structure. Crystal growth of large size single-crystals of metals and alloys was used for preparation of specimens with mosaic structure suitable for neutron monochromator and polarizer systems. The construction work of the Neutron and Gamma Radiography Station has been completed. The results of first tests and studies proved the expected abilities of the systems.

    1990-01-01

    This book fills a gap in current literature by covering the increasing nuclear physics content of various A-level syllabuses. In section 1 we outline the background and early development of the subject, in section 2 we deal with nuclear properties and theories at a level suitable for the pre-university student. The majority of topics have been treated with the limited use of mathematics, this necessitating some simplification which we hope to have accomplished without undue error. A few topics have been developed mathematically, to some extent, e.g. series decay. While it is the purpose of a book at this level to introduce the reader to the facts and theories of nuclear physics, we have to recognise that any teacher of science, at any level, must attempt to instill in the young scientist a sense of responsibility and an understanding of the problems attendant on the technological applications are important. These problems have been touched on in the text but we hope the student will be persuaded to read further; for this purpose we have added a short list of suggested additional reading. A selection of A-level past paper questions has been included. (author)

    Today the applications of nuclear physics span a very broad range of topics and fields. This review discusses a number of aspects of these applications, including selected topics and concepts in nuclear reactor physics, nuclear fusion, nuclear non-proliferation, nuclear-geophysics, and nuclear medicine. The review begins with a historic summary of the early years in applied nuclear physics, with an emphasis on the huge developments that took place around the time of World War II, and that underlie the physics involved in designs of nuclear explosions, controlled nuclear energy, and nuclear fusion. The review then moves to focus on modern applications of these concepts, including the basic concepts and diagnostics developed for the forensics of nuclear explosions, the nuclear diagnostics at the National Ignition Facility, nuclear reactor safeguards, and the detection of nuclear material production and trafficking. The review also summarizes recent developments in nuclear geophysics and nuclear medicine. The nuclear geophysics areas discussed include geo-chronology, nuclear logging for industry, the Oklo reactor, and geo-neutrinos. The section on nuclear medicine summarizes the critical advances in nuclear imaging, including PET and SPECT imaging, targeted radionuclide therapy, and the nuclear physics of medical isotope production. Lastly, each subfield discussed requires a review article unto itself, which is not the intention of the current review; rather, the current review is intended for readers who wish to get a broad understanding of applied nuclear physics.

  7. A new physics-based method for detecting weak nuclear signals via spectral decomposition

    International Nuclear Information System (INIS)

    Chan, Kung-Sik; Li, Jinzheng; Eichinger, William; Bai, Erwei

    2012-01-01

    We propose a new physics-based method to determine the presence of the spectral signature of one or more nuclides from a poorly resolved spectra with weak signatures. The method is different from traditional methods that rely primarily on peak finding algorithms. The new approach considers each of the signatures in the library to be a linear combination of subspectra. These subspectra are obtained by assuming a signature consisting of just one of the unique gamma rays emitted by the nuclei. We propose a Poisson regression model for deducing which nuclei are present in the observed spectrum. In recognition that a radiation source generally comprises few nuclear materials, the underlying Poisson model is sparse, i.e. most of the regression coefficients are zero (positive coefficients correspond to the presence of nuclear materials). We develop an iterative algorithm for a penalized likelihood estimation that prompts sparsity. We illustrate the efficacy of the proposed method by simulations using a variety of poorly resolved, low signal-to-noise ratio (SNR) situations, which show that the proposed approach enjoys excellent empirical performance even with SNR as low as to -15 db.

    Soil (ground) and vegetative covers of the Earth are one of the most responsive and specific parts of the biosphere with respect to pollution. A proper control after them is of fundamental importance in creating and protecting optical surrounding. Analysis of soils and plants is a necessary and important stage in the process of investigation of microelements' migration in biogeochemical cycles. For this purpose we studied some reserved terrains of Uzbekistan to reveal a level of their contamination by heavy metals, as well as to find out typical and territorial singularities in accumulation of a number of elements by soils and plants. In order to decrease an influence of systematic errors, and to obtain more precise and reliable data, we carried out the element analysis of the samples by different methods, such as gamma-activation analysis, neutron-activation analysis, X-ray spectral analysis, and X-ray fluorescent analysis. As a result of our investigations we have obtained rather great information, which can be used in future to estimate the conditions of the surrounding nature. The investigations allowed us to determine the content of about 40 elements, as well as to show that the data, obtained by different nuclear-physical methods, are in rather good agreement. A reproducibility of the results of the methods, determined in control measurements, depends on the concentration of the analyzed elements, and is equal to 10-35 %. A comparison of the obtained data allowed us to reveal some singularities in element composition of the investigated samples depending on their type and territorial factor. It has been revealed that the data, obtained by different methods, are in rather good agreement. Our investigations allowed us to find out a series of regularities and singularities in accumulation of elements in plants, as well as to show the possibility of using nuclear-physical methods in such investigations

    1999-01-01

    A simple review of strangeness nuclear physics is stated in the order of introduction, generation, structure and decay of hyper-nucleus and S=-2 nuclear physics. Strangeness nuclear physics investigate the structure and nuclear force of new created nucleus by introducing strangeness to the nuclear matter. The fundamental problems are hyperon-nucleon and hyperon-hyperon interaction. There are many methods to generate hyper nucleus. The stopped K - reaction is the best one. Λ and S hyper and S=-2 nucleus were generated by (K - , π) and (π + , K + ) reaction, (K - , π) reaction and (K - , K + ) reaction, respectively. The elementary decay process in the nucleus is Λ - > pπ (Q=38 MeV), nπ 0 and Λp - > np (Q=176 MeV), Λn- > nn. In emulsion, mass of light nucleus less than 160 were determined. Two measurement units are stated. One of them is a double focusing type K beam line in BNL to investigate H dibaryon by (K - , K + ) reaction. The other is KEK-SKS, which is superconducting kaon spectrometer to study hyper nucleus by (π + , K + ) reaction. The various kinds of binding energy of Λ single-particle states are displayed as a function of A -2/3 . These experimental data fit well with DWIA calculation using Woods-Saxon type one-body potential. A spectrum of 12C (π + , K + ) reaction showed small peak without main two peaks, which was a hyperfine structure between the exited state of 11 C core and couple of s 1/2 Λ. Although γ-ray was detected by three nucleuses such as 4 HΛ, 7 Li Λ and 9 Be Λ , γ-ray spectrometry of hyper nucleus remains unexplored. E hyper nucleus is detected by 4He(K-, t) and not by 4 He (K - , π + ). The binding energy of 4He Σ is 4.4 + 1 MeV and the width 7.0 + 0.7 MeV. Λ hyper nucleus decay is occurred by weak interaction. The elementary processes are a mesonic decay of Λ - > pπ - and Λ - > nπ 0 and a nonmesonic decay of Λn - > nn and Λp- > np. The lifetime of hyper nucleus is shorter than free Λ.

    Nuclear astrophysics, a fruitful combination of nuclear physics and astrophysics can be viewed as a special application of nuclear physics where the study of nuclei and their reactions are motivated by astrophysical problems. Nuclear astrophysics is also a good example for the state of the art interdisciplinary research. The origin of elements studied by geologists is explored by astrophysicists using nuclear reaction rates provided by the nuclear physics community. Due to the high interest in the field two recent Nuclear Physics Divisional Conferences of the European Physical Society were devoted to nuclear astrophysics and a new conference series entitled 'Nuclear Physics in Astrophysics' has been established. Selected problems of nuclear astrophysics will be presented emphasizing the interplay between nuclear physics and astrophysics. As an example the role of 14 N(p,r) 15 O reaction rate in the determination of the age of globular clusters will be discussed in details

    Highlights: • Review of the numerical methods used for the multi-physics temporal coupling. • Review of high-order improvements to the Operator Splitting coupling method. • Analysis of truncation error due to the temporal coupling. • Recommendations on best-practice approaches for multi-physics temporal coupling. - Abstract: The advanced numerical simulation of a realistic physical system typically involves multi-physics problem. For example, analysis of a LWR core involves the intricate simulation of neutron production and transport, heat transfer throughout the structures of the system and the flowing, possibly two-phase, coolant. Such analysis involves the dynamic coupling of multiple simulation codes, each one devoted to the solving of one of the coupled physics. Multiple temporal coupling methods exist, yet the accuracy of such coupling is generally driven by the least accurate numerical scheme. The goal of this paper is to review in detail the approaches and numerical methods that can be used for the multi-physics temporal coupling, including a comprehensive discussion of the issues associated with the temporal coupling, and define approaches that can be used to perform multi-physics analysis. The paper is not limited to any particular multi-physics process or situation, but is intended to provide a generic description of multi-physics temporal coupling schemes for any development stage of the individual (single-physics) tools and methods. This includes a wide spectrum of situation, where the individual (single-physics) solvers are based on pre-existing computation codes embedded as individual components, or a new development where the temporal coupling can be developed and implemented as a part of code development. The discussed coupling methods are demonstrated in the framework of LWR core analysis

    Heavy ion accelerators are used not only for the synthesis of new elements but also for the production of nuclear filters from polymers. The principle is described of the manufacture of such filters, and their chemical processing. By changes in irradiation conditions and in conditions of chemical leaching, nuclear filters may be obtained of various density, shape and size of pores and with a different angular distribution of tracks in the polymer material. The most frequently used polymer is polyethylene terephthalate film. The uses are described of nuclear filters, such as water treatment in the production of semiconductor instruments, in cryogenic instruments, in the purification concentration and sterilization filtration of viruses and vaccines, etc. Other uses of heavy ion beams are suggested, such as the method of nuclear tracks, the manufacture of membranes with a single opening, the manufacture of laser diaphragms, lithography, etc. (E.S.)

    The Department of Energy's Nuclear Physics program is a comprehensive program of interdependent experimental and theoretical investigation of atomic nuclei. Long range goals are an understanding of the interactions, properties, and structures of atomic nuclei and nuclear matter at the most elementary level possible and an understanding of the fundamental forces of nature by using nuclei as a proving ground. Basic ingredients of the program are talented and imaginative scientists and a diversity of facilities to provide the variety of probes, instruments, and computational equipment needed for modern nuclear research. Approximately 80% of the total Federal support of basic nuclear research is provided through the Nuclear Physics program; almost all of the remaining 20% is provided by the National Science Foundation. Thus, the Department of Energy (DOE) has a unique responsibility for this important area of basic science and its role in high technology. Experimental and theoretical investigations are leading us to conclude that a new level of understanding of atomic nuclei is achievable. This optimism arises from evidence that: (1) the mesons, protons, and neutrons which are inside nuclei are themselves composed of quarks and gluons and (2) quantum chromodynamics can be developed into a theory which both describes correctly the interaction among quarks and gluons and is also an exact theory of the strong nuclear force. These concepts are important drivers of the Nuclear Physics program

    The theoretical physics program in the Physics Division at ORNL involves research in both nuclear and atomic physics. In nuclear physics there is extensive activity in the fields of direct nuclear reactions with light- and heavy-ion projectiles, the structure of nuclei far from stability and at elevated temperatures, and the microscopic and macroscopic description of heavy-ion dynamics, including the behavior of nuclear molecules and supernuclei. New research efforts in relativistic nuclear collisions and in the study of quark-gluon plasma have continued to grow this year. The atomic theory program deals with a variety of ionization, multiple-vacancy production, and charge-exchange processes. Many of the problems are selected because of their relevance to the magnetic fusion energy program. In addition, there is a joint atomic-nuclear theory effort to study positron production during the collision of two high-Z numbers, i.e., U+U. A new Distinguished Scientist program, sponsored jointly by the University of Tennessee and ORNL, has been initiated. Among the first appointments is G.F. Bertsch in theoretical physics. As a result of this appointment, Bertsch and an associated group of four theorists split their time between UT and ORNL.

    1993-10-01

    A new method, which is non-contact on measured water level, for measuring high pressure steam manifold water level with nuclear detection technique is introduced. This method overcomes the inherent drawback of previous water level gauges based on other principles. This method can realize full range real time monitoring on the continuous water level of high pressure steam manifold from the start to full load of boiler, and the actual value of water level can be obtained. The measuring errors were analysed on site. Errors from practical operation in Tianjin Junliangcheng Power Plant and in laboratory are also presented

    The author proposes an overview of the main notions related to nuclear physics. He first addresses the atom and the nucleus: brief history, their constituents, energetic aspects for electrons and nucleus. The second part deals with radioactivity: definitions, time law and conservation law, natural and artificial radio-elements, α, β and γ radiations. Nuclear reactions (fission and fusion) are then presented as well as their application to nuclear reactor operation. The next part concerns interactions between radiations and matter, more precisely between charged particles and matter, neutrons and matter, X rays or γ rays and matter. The last chapter presents the various quantities used to characterise a source, the radiation field and the physical action, and quantities and units used in radiobiology and in radiation protection

  5. Physics and nuclear power

    International Nuclear Information System (INIS)

    Buttery, N E

    2008-01-01

    Nuclear power owes its origin to physicists. Fission was demonstrated by physicists and chemists and the first nuclear reactor project was led by physicists. However as nuclear power was harnessed to produce electricity the role of the engineer became stronger. Modern nuclear power reactors bring together the skills of physicists, chemists, chemical engineers, electrical engineers, mechanical engineers and civil engineers. The paper illustrates this by considering the Sizewell B project and the role played by physicists in this. This covers not only the roles in design and analysis but in problem solving during the commissioning of first of a kind plant. Looking forward to the challenges to provide sustainable and environmentally acceptable energy sources for the future illustrates the need for a continuing synergy between physics and engineering. This will be discussed in the context of the challenges posed by Generation IV reactors

    This report describes the accomplishments in basic research in nuclear physics carried out by the theoretical nuclear physics group in the Department of Physics at the University of Texas at Austin, during the period of November 1, 1992 to October 31, 1993. The work done covers three separate areas, low-energy nuclear reactions, intermediate energy physics, and nuclear structure studies. Although the subjects are thus spread among different areas, they are based on two techniques developed in previous years. These techniques are a powerful method for continuum-random-phase-approximation (CRPA) calculations of nuclear response and the breakup-fusion (BF) approach to incomplete fusion reactions, which calculation on a single footing of various incomplete fusion reaction cross sections within the framework of direct reaction theories. The approach was developed as a part of a more general program for establishing an approach to describing all different types of nuclear reactions, i.e., complete fusion, incomplete fusion and direct reactions, in a systematic way based on single theoretical framework

  7. Advances in nuclear physics

    CERN Document Server

    Vogt, Erich

    1975-01-01

    Review articles on three topics of considerable current interest make up the present volume. The first, on A-hypernuclei, was solicited by the editors in order to provide nuclear physicists with a general description of the most recent developments in a field which this audience has largely neglected or, perhaps, viewed as a novelty in which a bizarre nuclear system gave some information about the lambda-nuclear intersection. That view was never valid. The very recent developments reviewed here-particularly those pertaining to hypernuclear excitations and the strangeness exchange reactions-emphasize that this field provides important information about the models and central ideas of nuclear physics. The off-shell behavior of the nucleon-nucleon interaction is a topic which was at first received with some embarrassment, abuse, and neglect, but it has recently gained proper attention in many nuclear problems. Interest was first focused on it in nuclear many-body theory, but it threatened nuclear physicists'comf...

    2010-01-01

    Nuclear science is at the very heart of the NNSA program. The energy produced by nuclear processes is central to the NNSA mission, and nuclear reactions are critical in many applications, including National Ignition Facility (NIF) capsules, energy production, weapons, and in global threat reduction. Nuclear reactions are the source of energy in all these applications, and they can also be crucial in understanding and diagnosing the complex high-energy environments integral to the work of the NNSA. Nuclear processes are complex quantum many-body problems. Modeling and simulation of nuclear reactions and their role in applications, coupled tightly with experiments, have played a key role in NNSA's mission. The science input to NNSA program applications has been heavily reliant on experiment combined with extrapolations and physical models 'just good enough' to provide a starting point to extensive engineering that generated a body of empirical information. This body of information lacks the basic science underpinnings necessary to provide reliable extrapolations beyond the domain in which it was produced and for providing quantifiable error bars. Further, the ability to perform additional engineering tests is no longer possible, especially those tests that produce data in the extreme environments that uniquely characterize these applications. The end of testing has required improvements to the predictive capabilities of codes simulating the reactions and associated applications for both well known and well characterized cases as well as incompletely known cases. Developments in high performance computing, computational physics, applied mathematics and nuclear theory have combined to make spectacular advances in the theory of fission, fusion and nuclear reactions. Current research exploits these developments in a number of Office of Science and NNSA programs, and in joint programs such as the SciDAC (Science Discovery through Advanced Computing) that

  13. Nuclear power reactor physics

    International Nuclear Information System (INIS)

    Barjon, Robert

    1975-01-01

    The purpose of this book is to explain the physical working conditions of nuclear reactors for the benefit of non-specialized engineers and engineering students. One of the leading ideas of this course is to distinguish between two fundamentally different concepts: - a science which could be called neutrodynamics (as distinct from neutron physics which covers the knowledge of the neutron considered as an elementary particle and the study of its interactions with nuclei); the aim of this science is to study the interaction of the neutron gas with real material media; the introduction will however be restricted to its simplified expression, the theory and equation of diffusion; - a special application: reactor physics, which is introduced when the diffusing and absorbing material medium is also multiplying. For this reason the chapter on fission is used to introduce this section. In practice the section on reactor physics is much longer than that devoted to neutrodynamics and it is developed in what seemed to be the most relevant direction: nuclear power reactors. Every effort was made to meet the following three requirements: to define the physical bases of neutron interaction with different materials, to give a correct mathematical treatment within the limit of necessary simplifying hypotheses clearly explained; to propose, whenever possible, numerical applications in order to fix orders of magnitude [fr

    Anchoring low-energy nuclear physics to the fundamental theory of strong interactions remains an outstanding challenge. I review the current progress and challenges of the endeavor to use lattice QCD to bridge this connection. This is a particularly exciting time for this line of research as demonstrated by the spike in the number of different collaborative efforts focussed on this problem and presented at this conference. I first digress and discuss the 2013 Ken Wilson Award.

    The D-T fusion cross-section is calculated using quantum mechanics with the model of square nuclear potential well and Coulomb potential barrier. The agreement between ENDF data and the theoretically calculated results is well in the range of 0.2-280 keV. It shows that the application of Breit-Wigner formula is not suitable for the case of the light nuclei fusion reaction. When this model is applied to the nuclear reaction between the charged particles confined in a lattice, it explains the 'abnormal phenomena'. It implies a prospect of nuclear fusion energy without strong nuclear radiations

  18. Nuclear Physics in Poland

    International Nuclear Information System (INIS)

    Wroblewski, A.K.

    2004-01-01

    Full text: This will be a short presentation of low and high energy nuclear physics in Poland, its history, essential results, and the present status. Nuclear physics in Poland has a tradition of hundred years. Research started just after the discovery of radium and polonium by Polish-born Maria Sklodowska-Curie and her husband Pierre Curie. Maria Sklodowska-Curie employed numerous Polish assistants in her Paris laboratory and supported radioactivity studies in Warsaw, her birth place, then under the occupation of tsarist Russia. In the first decades of the XXth century Poland was one of the leading countries in radioactivity studies. In the late 1930-ies a cyclotron was constructed in Warsaw and an ambitious 'Star of Poland' project was launched to study the cosmic rays. Unfortunately, the Second World War stopped all scientific activity in Poland. A large fraction of Polish physicists perished in the period 1939-1945. After the World War nuclear physics of low and high energy was rebuilt in Warsaw and Krakow. Already in 1952 Marian Danysz and Jerzy Pniewski discovered the first hypernucleus. This important discovery was essential to understand the properties of numerous new particles found in cosmic rays. Polish physicists entered intensive collaboration with both CERN and Dubna and took part also in research at other centers in Europe (DESY, GSI, GANIL, Julich, SACLAY) and the United States (Fermilab). At present the research is concentrated in Warsaw and Krakow (the two largest centers), and smaller teams, mostly theorists, are also in Bialystok, Katowice, Kielce, Lublin, Lodz and Wroclaw. Several years ago a heavy ion cyclotron was built in Warsaw. Among the important discoveries made by Polish nuclear physicists one may mention the theoretical works on superheavy elements and the recent discovery of the two-proton radioactivity

    2011-01-01

    The field of nuclear medicine is expanding rapidly, with the development of exciting new diagnostic methods and treatments. This growth is closely associated with significant advances in radiation physics. In this book, acknowledged experts explain the basic principles of radiation physics in relation to nuclear medicine and examine important novel approaches in the field. The first section is devoted to what might be termed the "building blocks" of nuclear medicine, including the mechanisms of interaction between radiation and matter and Monte Carlo codes. In subsequent sections, radiation sources for medical applications, radiopharmaceutical development and production, and radiation detectors are discussed in detail. New frontiers are then explored, including improved algorithms for image reconstruction, biokinetic models, and voxel phantoms for internal dosimetry. Both trainees and experienced practitioners and researchers will find this book to be an invaluable source of up-to-date information.

    The authors report on recent progress of research at the interface of nuclear physics and astrophysics. During the past year, the authors continued to work on Big Bang and stellar nucleosynthesis, the solar neutrino problem, the equation of state for dense matter, the quark-hadron phase transition, and the origin of gamma-ray bursts; and began studying the consequences of nuclear reaction rates in the presence of strong magnetic fields. They have shown that the primordial production of B and Be cannot explain recent detections of these elements in halo stars and have looked at spallation as the likely source of these elements. By looking at nucleosynthesis with inhomogeneous initial conditions, they concluded that the Universe must have been very smooth before nucleosynthesis. They have also constrained neutrino oscillations and primordial magnetic fields by Big Bang nucleosynthesis. On the solar neutrino problem, they have analyzed the implications of the SAGE and GALLEX experiments. They also showed that the presence of dibaryons in neutron stars depends weakly on uncertainties of nuclear equations of state. They have started to investigate the consequences of strong magnetic fields on nuclear reactions and implications for neutron star cooling and supernova nucleosynthesis

    International Nuclear Information System (INIS)

    2006-01-01

    Yukawa and Tomonaga made epoch-making contributions to the development of elementary particle physics; Yukawa proposed the meson theory of the nuclear force and Tomonaga developed renormalization theory in QED. The nuclear force is, of course, the basis of all nuclear physics. In this sense, Yukawa's work set the foundations for nuclear physics. Tomonaga worked in his late years on problems of collective motion appearing in many many-particle-systems, nuclear systems being one of the examples. Yukawa and Tomonaga were also deeply involved in founding the Institute of Fundamental Physics and Institute for Nuclear Study, through which they made invaluable contributions to the development of the field of nuclear physics. It is almost impossible to report in this short article on all of what they have achieved and thus I would like to discuss here their contributions to nuclear physics only in a limited scope, based on my personal reminiscence of them.

  4. Nuclear physics and cosmology

    Schramm, D.N.

    1989-12-01

    Nuclear physics has provided one of the 2 critical observational tests of all Big Bang cosmology, namely Big Bang Nucleosynthesis. Furthermore, this same nuclear physics input enables a prediction to be made about one of the most fundamental physics questions of all, the number of elementary particle families. This paper reviews the standard Big Bang Nucleosynthesis arguments. The primordial He abundance is inferred from He--C and He--N and He--O correlations. The strengthened Li constraint as well as 2 D plus 3 He are used to limit the baryon density. This limit is the key argument behind the need for non-baryonic dark matter. The allowed number of neutrino families, N ν , is delineated using the new neutron lifetime value of τ n = 890 ± 4s (τ 1/2 = 10.3 min). The formal statistical result is N ν = 2.6 ± 0.3 (1σ) providing a reasonable fit (1.3σ) to 3 families but making a fourth light (m ν approx-lt 10 MeV) neutrino family exceedingly unlikely (approx-gt 4.7σ) (barring significant systematic errors either in D + 3 He, and Li and/or 4 He and/or τ n ). It is also shown that uncertainties induced by postulating a first-order quark-hadron phase transition do not seriously affect the conclusions. 21 refs., 3 figs

The formal statistical result is N(nu) = 2.6 + or - 0.3 (1 sigma), providing a reasonable fit (1.3 sigma) to three families but making a fourth light (m(nu) less than or equal to 10 MeV) neutrino family exceedly unlikely (approx. greater than 4.7 sigma). It is also shown that uncertainties induced by postulating a first-order quark-baryon phase transition do not seriously affect the conclusions.

    Starting from Adler's low-energy theorem for the soft pion production amplitudes the predictions of the meson exchange currents theory for the nuclear physics are discussed. The results are reformulated in terms of phenomenological lagrangians. This method allows one to pass naturally to the more realistic case of hard mesons. The predictions are critically compared with the existing experimental data. The main processes in which vector isovector exchange currents, vector isoscalar exchange currents and axial exchange currents take place are pointed out

    We have investigated a variety of research topics on the interface of nuclear physics and astrophysics during the past year. We have continued our study of dihyperon states in dense matter and have started to make a connection between their properties in the core of neutron stars with the ongoing experimental searches at Brookhaven National Laboratory. We started to build a scenario for the origin of gamma-ray bursts using the conversion of neutron stars to strange stars close to an active galactic nucleous. We have been reconsidering the constraints due to neutron star cooling rates on the equation of state for high density matter in the light, of recent findings which show that the faster direct Urca cooling process is possible for a range of nuclear compositions.

    We have investigated a variety of research topics on the interface of nuclear physics and astrophysics during the past year. We have continued our study of dihyperon states in dense matter and have started to make a connection between their properties in the core of neutron stars with the ongoing experimental searches at Brookhaven National Laboratory. We started to build a scenario for the origin of gamma-ray bursts using the conversion of neutron stars to strange stars close to an active galactic nucleous. We have been reconsidering the constraints due to neutron star cooling rates on the equation of state for high density matter in the light, of recent findings which show that the faster direct Urca cooling process is possible for a range of nuclear compositions. We have developed a model for the formation of primordial magnetic fields due to the dynamics of the quark-hadron phase transition.

    This item documents the International Conference on Nuclear and Particle Physics held at the University of Glasgow, UK, from 30th March to 1st April 1993. It was organised by the Department of Physics and Astronomy at Glasgow University on behalf of the Nuclear and Particle Physics Division of the Institute of Physics. The scientific programme covered many areas of current interest in nuclear and particle physics. Particle physics topics included up to the minute reports on the physics currently coming from CERN'S Low Energy Antiproton Ring (LEAR), Hadron-Elektron-Ring Analage (HERA) and Large Electron-Positron Storage Rings (LEP), and reviews of quantum chromodynamics (QCD) lattice gauge theory. Looking to the future the programme covered the search for the Higgs boson and a review of physics experiments planned for the new generation of accelerators at Large Hadron Collider (LHC) and Superconducting Supercollider (SSC). The conference coincided with the final closure of the world class Nuclear Structure Facility at Daresbury and marked the transition of United Kingdom (UK) nuclear physics research into a new era of international collaboration. Several talks described new international collaborative research programmes in nuclear physics initiated by UK scientists. The conference also heard of new areas of nuclear physics which will in future be opened up by high energy continuous beam electron accelerators and by radioactive ion beam accelerators. (author)

  2. Developing new methods to investigate nuclear physics input to the cosmological lithium problem

    Directory of Open Access Journals (Sweden)

    Cook K.J.

    2013-12-01

    Full Text Available A significant challenge to nuclear astrophysics is the cosmological lithium problem, where models of Big Bang nucleosynthesis indicate abundances of 7Li two to four times larger than what is inferred via spectroscopic measurements of metal-poor stars. Recent experimental techniques developed for nuclear reaction studies at energies near the fusion barrier, if extended to reactions of astrophysical interest, may help understand nuclear reactions that can affect the production of 7Li during the Big Bang. Experiments at the ANU, using new experimental techniques, have provided complete pictures of the breakup mechanisms of light nuclei in collisions with heavy targets, such as 208Pb and 209Bi [1]. These experiments revealed dominant breakup mechanisms which had not even been considered in theoretical models. The study of the breakup of 6Li and 7Li following interactions with 58,64Ni and 27Al acts as a stepping stone from this previous work towards future experimental studies of breakup reactions of astrophysical relevance. In all cases studied, breakup is dominantly triggered by nucleon transfer between the colliding partners, but the transfer mechanisms are different. The findings of these experiments and experimental considerations for extensions to reactions of light nuclei, such as d +7Be, will be presented.

    Moshe Feldenkrais is known from the textbooks as a collaborator of Joliot-Curie, Langevin, and Kowarski participating in the first nuclear fission experiments. During the war he went to Great Britain and worked on the development of submarine detection devices. From experimental physics, following finally a suggestion of Lew Kowarski, he turned his interest to neurophysiology and neuropsychology. He studied the cybernetical organisation between human body dynamics and the mind. He developed his method known as "Functional integration" and "Awareness through movement". It has been applied with surprising results to post-traumatic rehabilitation, psychotherapy, re-education of the mentally or physically handicapped, and improvement of performance in sports. It can be used by everybody who wants to discover his natural grace of movement.

    Element composition of precipitation accumulated in natural areas (snow, peat) is investigated by neutron activation technique using nuclear reactor. Content of microelements (Fe, Co, Sc, Au, Hg, Sb, Br, Na) is determined in both maximal contamination industrial area and at a distance more, than 40 km from the area. Snow cover and peat occurrence are shown to be convenient substrates to investigate contamination of the industrial centre vicinities in space and time. Standard development of MPC (maximum permissible concentration) contents of industrial dust ingredients, especially toxic ones, in these substrates allows to solve quickly many problems raised by environmental monitoring. 10 refs.; 2 tabs

  7. The Relevance of Nuclear Physics

    Weisskopf, V.F.

    1969-01-01

    I am asked what nuclear physics is about, that is, nuclear physics as distinct from particle physics and other parts of physics. I see three trends in this science. One is the discovery of new phenomena, phenomena of nature which we have not seen or observed, of which we did not know anything before. The second trend, I would say, is towards the solution of fundamental problems, the answers to certain basic questions in physics; I shall give some details later on. The third is the construction of new concepts in physics necessary to deal with the problems not only in nuclear physics but also in the rest of physics. The order of these three items is unimportant. This meeting should be concerned not only with the factual questions of science, but also with the, let me say, philosophic and practical questions of nuclear physics. Why do we do nuclear physics, what is the sense of it, what is the meaning of it and, most importantly, how can we defend the support of nuclear physics, how can we convince the governments to spend money on such a thing, which to a certain extent is our pleasure? And so we will have to be quite clear among ourselves that this is a very important matter

    Meyer, Harvey

    2015-01-01

    With ever increasing computational resources and improvements in algorithms, new opportunities are emerging for lattice gauge theory to address key questions in strongly interacting systems, such as nuclear matter. Calculations today use dynamical gauge-field ensembles with degenerate light up/down quarks and the strange quark and it is possible now to consider including charm-quark degrees of freedom in the QCD vacuum. Pion masses and other sources of systematic error, such as finite-volume and discretization effects, are beginning to be quantified systematically. Altogether, an era of precision calculation has begun, and many new observables will be calculated at the new computational facilities.  The aim of this set of lectures is to provide graduate students with a grounding in the application of lattice gauge theory methods to strongly interacting systems, and in particular to nuclear physics.  A wide variety of topics are covered, including continuum field theory, lattice discretizations, hadron spect...

    1992-01-01

    Recently developed facilities allow a wide range of new investigations of the reactions and properties of short-lived nuclei. These studies may help to solve puzzles of nuclear structure and the Big Bang. The purpose of nuclear physics is to measure properties of specific nuclides and infer from them global properties common to all nuclides. One goal, for example, is to understand nuclear sizes and matter distributions in terms of basic nuclear forces. Another is to understand the variation throughout the periodic table of the dominant quantum states, which are known as the open-quotes nuclear shell modelclose quotes states and are characterized, much as are atomic states, by a principal quantum number and by orbital and total angular momentum quantum numbers. In turn other nuclear phenomena, such as the collective excitations known as giant resonances, can be understood in terms of the shell-model configurations and basic nuclear parameters. Radioactive nuclear beam studies of reactions of short-lived nuclides have already yielded results with important ramifications in both nuclear physics and astrophysics. Nuclear physicists expect unstable nuclides to exhibit unusual structures or features that may test their understanding of known nuclear phenomena at extreme conditions, and perhaps even to reveal previously unknown nuclear phenomena, Astrophysicists, for their part, have known for several decades that processes in both Big Bang nucleosynthesis and stellar nucleosynthesis involve short-lived nuclides. Indeed, the original motivation for developing radioactive nuclear beams was astrophysical. 25 refs., 7 figs

    1998-01-01

    Results are presented of several year investigation to study possibilities of the NPMA for the determination of vanadium in organic fossils and applications of these methods to scientific and practical tasks. For these purposes, various versions of activation analysis (AA), X-ray fluorescence analysis (XRFA), electron spin resonance (ESR) spectroscopy and atomic emission with inductively coupled plasma spectroscopy (AES-ICP). Advantages and pitfalls of individual methods are discussed. The techniques developed can be used for estimation and calculation of stocks of vanadium in organic fossils at the territories of Kazakstan, Tatarstan and along the Volga-river. Analysis results helped in discovering new, industrially important deposits of this valuable metal. Quantitative determination of vanadium was carried out at different stages of technological processes of its extraction from high-viscous oils and oil-bitumen rocks. Results of analyses allowed to reveal the most effective versions of technologies of demetallization of these fossils. Content of vanadium was also studied in different locations of high-viscous oil deposits being explored by the method of inside-stratum burning. Results of analyses showed that the concentration of vanadium in oil decreases considerably with increasing temperature, that is, a considerable part of vanadium (up to 60 percent) may be lost irretrievably. Thus, for the exploration of these deposits a method of vapor-thermal influence onto the stratum was recommended, by using of which the loss of vanadium is insignificant

  17. Nuclear physics: Macroscopic aspects

    International Nuclear Information System (INIS)

    Swiatecki, W.J.

    1993-12-01

    A systematic macroscopic, leptodermous approach to nuclear statics and dynamics is described, based formally on the assumptions ℎ → 0 and b/R << 1, where b is the surface diffuseness and R the nuclear radius. The resulting static model of shell-corrected nuclear binding energies and deformabilities is accurate to better than 1 part in a thousand and yields a firm determination of the principal properties of the nuclear fluid. As regards dynamics, the above approach suggests that nuclear shape evolutions will often be dominated by dissipation, but quantitative comparisons with experimental data are more difficult than in the case of statics. In its simplest liquid drop version the model exhibits interesting formal connections to the classic astronomical problem of rotating gravitating masses

    Most elements are synthesized, or ""cooked"", by thermonuclear reactions in stars. The newly formed elements are released into the interstellar medium during a star's lifetime, and are subsequently incorporated into a new generation of stars, into the planets that form around the stars, and into the life forms that originate on the planets. Moreover, the energy we depend on for life originates from nuclear reactions that occur at the center of the Sun. Synthesis of the elements and nuclear energy production in stars are the topics of nuclear astrophysics, which is the subject of this book

    Nuclear physics is the study of the heavy but tiny nucleus that lies at the centre of all atoms and makes up 99.9 per cent by weight of everything we see. There are many applications of nuclear physics including direct contributions to medicine and industry, such as the use of radioactive isotopes as diagnostic tracers, or of beams of nuclei for tailoring the properties of semiconductors. More indirectly, ideas and concepts of nuclear physics have influence in many corners of modern science and technology. Physicists in the UK have a long tradition in nuclear physics, and have developed a world-wide reputation for the excellence of their work.

    Paetz gen Schieck, Hans

    2012-01-01

    The measurement of spin-polarization observables in reactions of nuclei and particles is of great utility and advantage when the effects of single-spin sub-states are to be investigated. Indeed, the unpolarized differential cross-section encompasses the averaging over the spin states of the particles, and thus loses details of the interaction process. This introductory text combines, in a single volume, course-based lecture notes on spin physics and on polarized-ion sources with the aim of providing a concise yet self-contained starting point for newcomers to the field, as well as for lecturers in search of suitable material for their courses and seminars. A significant part of the book is devoted to introducing the formal theory-a description of polarization and of nuclear reactions with polarized particles. The remainder of the text describes the physical basis of methods and devices necessary to perform experiments with polarized particles and to measure polarization and polarization effects in nuclear rea...

    I am pleased to be able to attend this symposium in honor of D. Allan Bromley and to see the new accelerator of the Yale University Nuclear Structure Laboratory. My talk on symmetry tests seems appropriate for this occasion: so much of the progress in this field depends on detailed knowledge of nuclear structure. The nuclear ''tricks'' that are played to filter and amplify interactions are possible because the nuclear spectroscopists have cataloged nuclear levels and determined their properties. I will describe how such nuclear structure studies may help to provide a window on physics beyond the standard model. My talk is not a summary of this subfield of nuclear physics. There is simply too much happening today to make a summary talk feasible. Instead, I have chosen four topics that I hope are representative of the field as a whole: parity mixing of nuclear states, time-reversal-odd nuclear moments, the Mikheyev-Smirnov enhancement of solar neutrino oscillations, and a nuclear experiment to monitor the long-term rate of stellar collapse in the galaxy. 39 refs., 5 figs., 1 tab

  16. Towards sustainable nuclear energy: Putting nuclear physics to work

    We have developed a new method to propagate the uncertainties of fundamental nuclear physics models and parameters to the design and performance parameters of future, clean nuclear energy systems. Using Monte Carlo simulation, it is for the first time possible to couple these two fields at the extremes of nuclear science without any loss of information in between. With the help of a large database of nuclear reaction measurements, we have determined the uncertainties of theoretical nuclear reaction models such as the optical, compound nucleus, pre-equilibrium and fission models. A similar assessment is done for the parameters that describe the resolved resonance range. Integrating this into one simulation program enables us to describe all open channels in a nuclear reaction, including a complete handling of uncertainties. Moreover, in one and the same process, values and uncertainties of nuclear reactor parameters are computed. This bypasses all the intermediate steps which have been used so far in nuclear data and reactor physics. Two important results emerge from this work: (a) we are able to quantify the required quality of theoretical nuclear reaction models directly from the reactor design requirements and (b) our method leads to a deviation from the commonly assumed normal distribution for uncertainties of safety related reactor parameters, and this should be taken into account for future nuclear energy development. In particular, calculated k eff distributions show a high-value tail for fast reactor spectra

    During the 30s and 40s of the last century atomic physicists discovered the fission of uranium nuclei bombarded by neutrons and realized the first self-sustaining controlled fission chain reaction, which ushered in the atomic age. After 50 years of electricity production, in 2003 nuclear power plants were generating 16% of the total electricity in the world. Of these, thermal neutron reactors make up over 99%. For the large scale production of nuclear power, say up to hundreds of GWe, it is very important to speed up the development and deployment of fast breeder reactors to avoid the future lack of uranium resources.

    Since the discovery of nuclear beta decay, nuclear physicists have studied the weak interaction and the nature of neutrinos. Many recent and current experiments have been focused on the elucidation of neutrino oscillations and neutrino mass. The quest for the absolute value of neutrino mass continues with higher precision studies of the tritium beta decay spectrum near the endpoint. Neutrino oscillations are studied through measurements of reactor neutrinos as a function of baseline and energy. And experiments searching for neutrinoless double beta decay seek to discover violation of lepton number and establish the Majorana nature of neutrino masses.

    1975-01-01

    Full text: An Advisory Group met to consider the up-dating and extension of the Recommendations for the Physical Protection of Nuclear Material, produced in 1972. Twenty-seven experts from 11 countries and EURATOM were present. Growing concern has been expressed in many countries that nuclear material may one day be used for acts of sabotage or terrorism. Serious attention is therefore being given to the need for States to develop national systems for the physical protection of nuclear materials during use, storage and transport throughout the nuclear fuel cycle which should minimize risks of sabotage or theft. The revised Recommendations formulated by the Advisory Group include new definitions of the objectives of national systems of physical protection and proposals for minimizing possibilities of unauthorized removal and sabotage to nuclear facilities. The Recommendations also describe administrative or organizational steps to be taken for this purpose and the essential technical requirements of physical protection for various types and locations of nuclear material, e.g., the setting up of protected areas, the use of physical barriers and alarms, the need for security survey, and the need of advance arrangements between the States concerned in case of international transportation, among others.

    The teaching of nuclear physics has a long history, particularly after the second world war, and the present author has 20 years of experience of teaching in that field. The research in nuclear physics has made major advances over the years, and the experiments become increasingly sophisticated. However, very often the university literature lags the development, as is, indeed, the case in all physics education. As a remedy of to-day, the didactic aspects are emphasized, especially at a basic level, while the curriculum content is. still left without upgrade. A standard textbook in basic nuclear physics is, while represent more modern theoretical treatises. The latter two, as their headings indicate, do not treat experimental methods, whereas has a presentation that illustrates methods and results with figures and references. However, they are from the 60 s and 70 s, they are old, and therefore cannot attract modern students of today. Consequently, one has the inevitable feeling that modern university teaching in nuclear physics, and the related area of nuclear safety, must be upgraded. A recent report in Finland, concluded that there is not sufficient nuclear safety education, but that on the other hand, it does not necessarily have to be connected with nuclear physics education, although this is recommendable. Further, the present Finnish university law states that 'The mission of the university shall be to promote free research and scientific and artistic education, to provide higher education based on research, and. to educate students to serve their country and humanity. In carrying out their mission, the universities shall interact with the surrounding society and promote the societal impact o research finding and artistic activities'. This mismatch between the curricula and the required 'societal impact' will be discussed, and examples of implications, usually not implemented, will be given. For nuclear physics specifically, the (lack of) connection between

    In the first years after the discovery of radioactivity it became clear that nuclear physics was, by excellence, the science of small quantum systems. Between the fifties and the eighties nuclear physics and elementary particles physics lived their own lives, without much interaction. During this period the basic concepts were defined. Recently, contrary to the specialization law often observed in science, the overlap between nuclear and elementary particle physics has become somewhat blurred. This Les Houches Summer School was set up with the aim of fighting off the excessive specialization evident in many international meetings, and return to the roots. The twofold challenge of setting up a fruitful exchange between experimentalists and theorists in the first place, and between nuclear and hadronic matter physicists in the second place was successfully met. The volume presents high quality, up-to-date reviews starting with an account of the birth and first developments of nuclear physics. Further chapters discuss the description of the nuclear structure, the physics of nuclei at very high spin, the existence of super-heavy nuclei as a consequence of shell structure, liquid-gas transition, including both a description and a review of the experimental situation. Other topics dealt with include the interactions between moderately relativistic heavy ions, the concept of a nucleon dressed by a cloud of pions, the presence of pions in the nucleus, the subnucleonic phenomena in nuclei and quark-gluons deconfinement transition, both theoretical and experimental aspects. Nuclear physics continues to influence many other fields, such as astrophysics, and is also inspired by these same fields. This cross-fertilisation is illustrated by the treatment of neutron stars in one of the final chapters. The last chapter provides an overview of a recent development in which particle and nuclear physicists have cooperated to revitalize an alternative method for nuclear energy

    The Science Faculty of the Comenius University in Bratislava established the nuclear physics specialization in 1962. Students enrolled in the study course acquired basic knowledge in mathematics and physics, foundations of the microstructure of matter and experimental methods of nuclear physics and technics. Since 1976 nuclear physics has been a separate study field which from the fourth year of study has its narrow specializations, namely applied nuclear physics, experimental nuclear physics and physics of the atomic nucleus and elementary particles. A change has recently been made in the system of optional lectures with the aim of providing the students with a wider range of knowledge in the physics of nuclear reactors and the use of computer technology and microelectronics in nuclear physics and technology. In 1980 a postgraduate study course was opened oriented to nuclear power and the environment. (E.S.)

    2011-01-01

    A one-term undergraduate course in reactor physics is described. The instructional format is strongly influenced by its intended audience of non-nuclear engineering students. In contrast to legacy treatments of the subject, the course focuses on the physics of nuclear power reactors with no attempt to include instruction in numerical methods. The multi-physics of power reactors is emphasized highlighting the close interactions between neutronic and thermal phenomena in design and analysis. Consequently, the material's sequencing also differs from traditional treatments, for example treating kinetics before the neutron diffusion is introduced. (author)

  11. Nuclear physics and ideas of quantum chaos

    International Nuclear Information System (INIS)

    Zelevinsky, V.G.

    2002-01-01

    The field nowadays called 'many-body quantum chaos' was started in 1939 with the article by I.I. Gurevich studying the regularities of nuclear spectra. The field has been extensively developed recently, both mathematically and in application to mesoscopic systems and quantum fields. We argue that nuclear physics and the theory of quantum chaos are mutually beneficial. Many ideas of quantum chaos grew up from the factual material of nuclear physics; this enrichment still continues to take place. On the other hand, many phenomena in nuclear structure and reactions, as well as the general problem of statistical physics of finite strongly interacting systems, can be understood much deeper with the help of ideas and methods borrowed from the field of quantum chaos. A brief review of the selected topics related to the recent development is presented

    Jones, O.E.

    1975-10-01

    Because of the increasing incidence of terrorism, there is growing concern that nuclear materials and facilities need improved physical protection against theft, diversion, or sabotage. Physical protection systems for facilities or transportation which have balanced effectiveness include information systems, access denial systems, adequate and timely response, recovery capability, and use denial methods for despoiling special nuclear materials (SNM). The role of these elements in reducing societal risk is described; however, it is noted that, similar to nuclear war, the absolute risks of nuclear theft and sabotage are basically unquantifiable. Sandia Laboratories has a major Energy Research and Development Administration (ERDA) role in developing advanced physical protection systems for improving the security of both SNM and facilities. These activities are surveyed. A computer simulation model is being developed to assess the cost-effectiveness of alternative physical protection systems under various levels of threat. Improved physical protection equipment such as perimeter and interior alarms, secure portals, and fixed and remotely-activated barriers is being developed and tested. In addition, complete prototype protection systems are being developed for representative nuclear facilities. An example is shown for a plutonium storage vault. The ERDA safe-secure transportation system for highway shipments of all significant quantities of government-owned SNM is described. Adversary simulation as a tool for testing and evaluating physical protection systems is discussed. A list of measures is given for assessing overall physical protection system performance. (auth)

    2016-01-01

    In the present volume of Journal of Physics: Conference Series we publish the proceedings of the “XXXIX Symposium on Nuclear Physics”, that was held from January 5-8, 2016 at the Hacienda Cocoyoc, Morelos, Mexico. The proceedings consist of 20 contributions that were presented as plenary talks at the meeting. The abstracts of all contributions, invited talks and posters, were published in the Conference Handbook. The Symposium on Nuclear Physics has a long and distinguished history. From the beginning it was intended to be a relatively small meeting designed to bring together some of the leading nuclear scientists in the field. Its most distinctive feature is to provide a forum for specialists in different areas of nuclear physics, both theorists and experimentalists, students, postdocs and senior scientists, in a relaxed and informal environment providing them with a unique opportunity to exchange ideas. After the first meeting in Oaxtepec in 1978, the Symposium was organized every year without interruption which makes the present one the 39th in a row. The scientific program consisted of 29 invited talks and a poster session on a wide variety of hot topics in contemporary nuclear physics, ranging from the traditional fields of nuclear structure and nuclear reactions to radioactive beams, nuclear astrophysics, hadronic physics, fundamental symmetries and relativistic heavy ions, as well as progress reports of large international projects like the HAWC Observatory in Puebla, Mexico, and the ATLAS and ALICE Collaborations of the LHC accelerator at CERN, Switzerland. In addition, there were several contributions highlighting interesting new results from foreign laboratories like Notre Dame, RIKEN, Jefferson Lab, Oak Ridge, INFN-Legnaro and INFN-LNS, as well as Mexican laboratories at ININ, LEMA and the Carlos Graef Laboratory at IF-UNAM. On the theoretical side there were talks on recent developments in nuclear structure, weakly bound nuclei, cluster models

    2011-01-01

    Nuclear astrophysics studies the physics of atomic nuclei, gravity, and thermodynamics in the early universe, stars and stellar explosions. Seventy years of nuclear science has allowed us to infer the origin of the chemical elements out of which our bodies and the Earth are made. We now believe that the lightest elements were created in nuclear reactions in the first three minutes after the big bang, and all the rest were made in nuclear reactions inside the stars and distributed throughout interstellar space via stellar winds and giant stellar explosions. I will show how a new generation of theoretical developments and experiments can shed light on the complex nuclear processes that control the evolution of stars and stellar explosions. (author)

    1984-01-01

    The experimental activities of the nuclear physics group at the University of Oslo have in 1983 as in the previous years mainly been centered around the SCANDITRONIX MC-35 cyclotron. The cyclotron has been in extensive use during the year for low-energy nuclear physics experiments. In addition it has been used for production of radionuclides for nuclear medicine, for experiments in nuclear chemistry and for corrosion and wear studies. After four years of operation, the cyclotron is still the newest nuclear accelerator in Scandinavia. The available beam energies (protons and alpha-particles up to 35 MeV and *sp3*He-particles up to 48 MeV, makes it a good tool for studies of highly excited low-spin states. The well developed on-line computer system has added to its usefulness. Most of the nuclear experiments during the year have been connected with the study of nuclear structure at high temperature. Experimens with the *sp3*He beam have given very interesting results. Theoretical studies have continued in the same field, and there has been a fruitful cooperation between experimental and theoretical physicists. Most of the experiments are performd as joint projects where physicists from two or three Nordic universities take part. (RF)

  12. Quark effects in nuclear physics

    International Nuclear Information System (INIS)

    Miller, G.A.

    1983-01-01

    A phenomenological approach which enables the size of quark effects in various nuclear processes is discussed. The principle of conservation of probability provides significant constraints on six quark wave functions. Using this approach, it is found that the low-energy proton-proton weak interaction can be explained in terms of W and Z boson exchanges between quarks. That the value of the asymptotic ratio of D to S state wave functions is influenced (at the 5% level) by quark effects, is another result of our approach. We have not discovered a nuclear effect that can be uniquely explained by quark-quark interactions. However it does seem that quark physics is very relevant for nuclear physics. 52 references

    An earlier study of unusual electromagnetic decays in (sup 86)Zr was extended in order to make comparisons with its isotone (sup 84)Sr and with (sup 84)Zr. The K=14 (t(sub 1/2) = 70 ns) high-spin isomer in (sup 176)W was found to have a 13 percent branch directly to the K=O ground-state band, one of the strongest violations of K-selection rules known. A new program to search for a predicted region of oblate deformation involving neutron deficient isotopes in the Rn/Fr/Ra region was begun. In the area of nuclear astrophysics, as part of a study of the onset of the rp-Process, a set of measurements searching for possible new resonances for (sup 14)O+(alpha) and (sup 17)F+p reactions was completed and a coincidence experiment measuring the (sup 19)F ((sup 3)He,t) (sup 19)Ne(alpha) (sup 15)O and (sup 19)F ((sup 3)He,t) (sup 19)Ne(p) (sup 18)F reactions in order to determine the rates of the (sup 18)F(p,(alpha)) (sup 15)O and (sup 18)F(p,(gamma)) (sup 19)Ne reactions was begun. Experimental measurements of (beta)n(alpha) coincidences from the (sup 15)N(d,p) (sup 16)N((beta)- (nu)) (sup 16)O((alpha)) (sup 12)C reaction have also been completed and are currently being analyzed to determine the rate of the (sup 12)C((alpha),(gamma)) reaction. In the APEX collaboration, we have completed the assembly and testing of two position-sensitive Na barrels which surround the axial silicon detector arrays and serve as the e(sup +) triggers by detecting their back-to-back annihilation quanta were completed. The HI@AGS and RHIC collaborations, construction and implementation activities associated with the space-time-tracker detector and in the design of the central detector for the PHENIX experiment were carried out. Operation of the ESTU tandem accelerator has been reliable, delivering beam on target at terminal voltages as high as 19.3 MV and running for as long as 143 days between tank openings. Fabrication and bench testing of a new negative ion source system have been completed.

    The operating electron accelerators and their importance in the nuclear and in the particle physics developments, are underlined. The principles of probing the nucleus by applying electron scattering techniques and the main experimental results, are summarized. In order to understand hadron interactions and the dynamics of quark confinement in nuclei, the high energy electrons must provide quantitative data on the following topics: the structure of the nucleon, the role of non nucleonic components in nuclei, the nature of short-range nucleon correlations, the origin of the short-range part of nuclear forces and the effects of the nuclear medium on quark distributions. To progress in the nuclear structure knowledge it is necessary to build a coherent strategy of accelerator developments in Europe

    The evolution of parallel processor supercomputers in recent years provides opportunities to investigate in detail many complex problems, in many branches of physics, which were considered to be intractable only a few years ago. But to take advantage of these new machines, one must have a better understanding of how the computers organize their work than was necessary with previous single processor machines. Equally important, the scientist must have this understanding as well as a good understanding of the structure of the physics problem under study. In brief, a new field of computational physics is evolving, which will be led by investigators who are highly literate both computationally and physically. A Center for Computationally Intensive Problems has been established with the collaboration of the University of Tennessee Science Alliance, Vanderbilt University, and the Oak Ridge National Laboratory. The objective of this Center is to carry out forefront research in computationally intensive areas of atomic, nuclear, particle, and condensed matter physics. An important part of this effort is the appropriate training of students. An early effort of this Center was to conduct a Summer School of Computational Atomic and Nuclear Physics. A distinguished faculty of scientists in atomic, nuclear, and particle physics gave lectures on the status of present understanding of a number of topics at the leading edge in these fields, and emphasized those areas where computational physics was in a position to make a major contribution. In addition, there were lectures on numerical techniques which are particularly appropriate for implementation on parallel processor computers and which are of wide applicability in many branches of science

    Atomic nuclei are made of nucleons, protons and neutrons, composed by quarks strongly interacting via gluons. How such complex objects as particles and nuclei are built? remains a fundamental question. A new "frontier" of subatomic physics is the exploration of exotic nuclei, elements and isotopes not stable enough to have survived on Earth. Exotic nuclei populated vast unknown regions of the nuclear chart where many unexpected structures have recently been discovered. Exotic nuclei synthesized in laboratory allow large variation of the neutron and proton chemical composition of nuclear systems needed to uncover the true nature of the subatomic structures and to understand the origin of elements in the Universe. This lecture will be an introduction to the open questions and key issues on the properties and structure of atomic nuclei and nuclear matter.

  10. Photonics applied to nuclear physics

    International Nuclear Information System (INIS)

    1985-01-01

    This was the second workshop held at the Council of Europe in the Nucleophot series. Its purpose was to bring together specialists from the fields of photonics and nuclear physics to discuss the application of modern optical techniques to current problems in experimental nuclear or particle physics research. Two techniques are particularly relevant and offer the possibility of major progress in the detection of extremely short-lived particles: holographic imaging of particle tracks and the development of scintillating-optical-fibre detectors. The discussions were mainly concerned with (a) the applications of holography to the large bubble chambers operating at Fermilab and (b) the development of high-resolution fibre-optic systems into high-rate microvertex detectors using scintillating core glass for both fixed-target and collider experiments in Europe and the USA. See hints under the relevant topics. (orig./HSI)

    1985-01-01

    A large fraction of the International Workshop on Hyperfine Interactions was devoted to various aspects of 'laser applications in nuclear physics'. This panel discussion took place before all of the relevant formal presentations on the subject were complete. Nevertheless, there had been sufficient discussions for the significance of this emerging area of hyperfine interaction research to be made clear. An attempt was made to identify critical and controversial aspects of the subject in order to critically evaluate past successes and indicate important future directions of research. Each of the panelists made a short statement on one phase of laser-nuclear physics research, which was followed by general discussions with the other panelists and the audience. In this report, a few areas which were not covered in the formal presentations are summarized: extensions of laser spectroscopy to shorter lifetimes; extension of laser techniques to nuclei far off stability; interpretation of laser spectroscopic data; sensitivity and spectral resolution; polarized beams and targets.

    1989-05-01

    The author surveys the range of nuclear physics issues which can be addressed with a high intensity hadron facility such as the KAON factory. He discusses hadron spectroscopy, kaon scattering, hypernuclear physics, spin physics, and nuclear physics with neutrinos. Nuclear Physics is defined rather broadly, encompassing the study of strongly interacting systems, and including the structure of individual hadrons, hadron-hadron interactions, hadronic weak and electromagnetic currents (in nuclei too), conventional nuclear structure, and exotic nuclei. The basic theme is how the KAON Factory can shed light on non-perturbative QCD and its relation to conventional nuclear physics

    International Nuclear Information System (INIS)

    Shubin, Yu.N.

    1974-01-01

    The paper outlines statistical methods which are widely used for describing properties of excited states of nuclei and nuclear reactions. It discusses physical assumptions lying at the basis of known distributions between levels (Wigner, Poisson distributions) and of widths of highly excited states (Porter-Thomas distribution, as well as assumptions used in the statistical theory of nuclear reactions and in the fluctuation analysis. The author considers the random matrix method, which consists in replacing the matrix elements of a residual interaction by random variables with a simple statistical distribution. Experimental data are compared with results of calculations using the statistical model. The superfluid nucleus model is considered with regard to superconducting-type pair correlations

    International Nuclear Information System (INIS)

    Furnstahl, R.J.

    2012-01-01

    Modern techniques of the renormalization group (RG) combined with effective field theory (EFT) methods are revolutionizing nuclear many-body physics. In these lectures we will explore the motivation for RG in low-energy nuclear systems and its implementation in systems ranging from the deuteron to neutron stars, both formally and in practice. Flow equation approaches applied to Hamiltonians both in free space and in the medium will be emphasized. This is a conceptually simple technique to transform interactions to more perturbative and universal forms. An unavoidable complication for nuclear systems from both the EFT and flow equation perspective is the need to treat many-body forces and operators, so we will consider these aspects in some detail. We'll finish with a survey of current developments and open problems in nuclear RG.

  1. [Research in theoretical nuclear physics

    International Nuclear Information System (INIS)

    Kapusta, J.I.

    1993-01-01

    The main subject of research was the physics of matter at energy densities greater than 0.15 GeV/fm 3 . Theory encompasses the relativistic many-body/quantum field theory aspects of QCD and the electroweak interactions at these high energy densities, both in and out of thermal equilibrium. Applications range from neutron stars/pulsars to QCD and electroweak phase transitions in the early universe, from baryon number violation in cosmology to the description of nucleus-nucleus collisions at CERN and at Brookhaven. Recent activity to understand the properties of matter at energy densities where the electroweak W and Z boson degrees of freedom are important is reported. This problem has applications to cosmology and has the potential to explain the baryon asymmetry produced in the big bang at energies where the particle degrees of freedom will soon be experimentally, probed. This problem is interesting for nuclear physics because of the techniques used in many-body, physics of nuclei and the quark-gluon plasma may be extended to this new problem. The was also interested in problems related to multiparticle production. This includes work on production of particles in heavy-ion collisions, the small x part, of the nuclear and hadron wave function, and multiparticle production induced by instantons in weakly coupled theories. These problems have applications in the heavy ion program at RHIC and the deep inelastic scattering experiments at HERA

    The experimental activities have in 1984 as in previous years mainly been centered around the cyclotron laboratory with the SCANDITRONIX MC-35 cyclotron. The available beam energies (protons and alpha-particles to 35 MeV and 3 He-particles up to 48 MeV) make it an excellent tool for studies of highly excited low-spin states, and also for other experiments with light ions in an intermediate energy range. During the year the accelerator has been in extensive use for low-energy nuclear physics experiments. Most of the experiments have been related to the study of nuclear structure at high temperature. Experiments with the 3 He-beam up to a particle energy of 45 MeV, have given some interesting results, which, it is hoped, will contribute to a better understanding of the cooling process in highly excited nuclei

  3. Nuclear methods in medicine

    International Nuclear Information System (INIS)

    Wolfe, D.M.

    1997-01-01

    Physicists have created remarkably sophisticated instruments for the performance of experiments. With variable phase lags many of these have become useful in technology. In the medical field NMD techniques have become commonplace under the rubric of Magnetic Resonance Imaging. Particle physics has developed sophisticated detectors for both charged and neutral particles. Many of these also have been adapted to medical uses. In both radiology and nuclear medicine, pixel detectors based on designs originating at large-scale colliders, are becoming highly useful in replacing film and NaI as the primary means of X-ray and (-ray detection. Coupled with high-speed work stations, these new techniques allow exciting new imagining modalities. Many of these are based on the handling of digital images originally developed for astronomy. Thus, once again, fundamental science is making large contributions to the development of technology. In this talk, various examples of developments in digital mammography and digital detectors for nuclear medicine will be given. The possibilities for telemedicine will be discussed. (author)

    Some of element contents in the samples have been determined by nuclear physical methods (XRFA, GAA and NAA). The possibility of determining Al, Si and Mg content in water samples has been studied. The detection limits of 0.03 mg/1 for Al, 0.3 mg/1 for Si and 0.1 mg/1 for Mg in water samples have been obtained. Monitoring of the aluminium and silicon content in water is important because the high concentration of aluminium or the low content of silicon in drinking water may be risk factors for Alzheimer's disease

  9. Physics of nuclear radiations concepts, techniques and applications

    CERN Document Server

    Rangacharyulu, Chary

    2013-01-01

    Physics of Nuclear Radiations: Concepts, Techniques and Applications makes the physics of nuclear radiations accessible to students with a basic background in physics and mathematics. Rather than convince students one way or the other about the hazards of nuclear radiations, the text empowers them with tools to calculate and assess nuclear radiations and their impact. It discusses the meaning behind mathematical formulae as well as the areas in which the equations can be applied. After reviewing the physics preliminaries, the author addresses the growth and decay of nuclear radiations, the stability of nuclei or particles against radioactive transformations, and the behavior of heavy charged particles, electrons, photons, and neutrons. He then presents the nomenclature and physics reasoning of dosimetry, covers typical nuclear facilities (such as medical x-ray machines and particle accelerators), and describes the physics principles of diverse detectors. The book also discusses methods for measuring energy a...

    2016-08-15

    The exploration of the QCD phase diagram is one of the most exciting and challenging projects of modern nuclear physics. In particular, the investigation of nuclear matter at high baryon densities offers the opportunity to find characteristic structures such as a first-order phase transition with a region of phase coexistence and a critical endpoint. The experimental discovery of these prominent landmarks of the QCD phase diagram would be a major breakthrough in our understanding of the properties of nuclear matter. Equally important is the quantitative experimental information on the properties of hadrons in dense matter which may shed light on chiral symmetry restoration and the origin of hadron masses. Worldwide, substantial efforts at the major heavy-ion accelerators are devoted to the clarification of these fundamental questions, and new dedicated experiments are planned at future facilities like CBM at FAIR in Darmstadt and MPD at NICA/JINR in Dubna. In this article the perspectives for MPD at NICA will be discussed. (orig.)

  12. Experimental techniques in nuclear and particle physics

    International Nuclear Information System (INIS)

    Tavernier, Stefaan

    2010-01-01

    The book is based on a course in nuclear and particle physics that the author has taught over many years to physics students, students in nuclear engineering and students in biomedical engineering. It provides the basic understanding that any student or researcher using such instruments and techniques should have about the subject. After an introduction to the structure of matter at the subatomic scale, it covers the experimental aspects of nuclear and particle physics. Ideally complementing a theoretically-oriented textbook on nuclear physics and/or particle physics, it introduces the reader to the different techniques used in nuclear and particle physics to accelerate particles and to measurement techniques (detectors) in nuclear and particle physics. The main subjects treated are: interactions of subatomic particles in matter; particle accelerators; basics of different types of detectors; and nuclear electronics. The book will be of interest to undergraduates, graduates and researchers in both particle and nuclear physics. For the physicists it is a good introduction to all experimental aspects of nuclear and particle physics. Nuclear engineers will appreciate the nuclear measurement techniques, while biomedical engineers can learn about measuring ionising radiation, the use of accelerators for radiotherapy. What's more, worked examples, end-of-chapter exercises, and appendices with key constants, properties and relationships supplement the textual material. (orig.)

    The method of reconstruction of interaction from the scattering data is formulated in the frame of the R-matrix theory in which the potential is determined by position of resonance Esub(lambda) and their reduced widths γ 2 lambda. In finite difference approximation for the Schroedinger equation this new approach allows to make the logics of the inverse problem IP more clear. A possibility of applications of IP formalism to various nuclear systems is discussed. (author)

  4. Nuclear methods for tribology

    International Nuclear Information System (INIS)

    Racolta, P.M.

    1994-01-01

    The tribological field of activity is mainly concerned with the relative movement of different machine components, friction and wear phenomena and their dependence upon lubrication. Tribological studies on friction and wear processes are important because they lead to significant parameter-improvements of engineering tools and machinery components. A review of fundamental aspects of both friction and wear phenomena is presented. A number of radioindicator-based methods have been known for almost four decades, differing mainly with respect to the mode of introducing the radio-indicators into the machine part to be studied. All these methods briefly presented in this paper are based on the measurement of the activity of wear products and therefore require high activity levels of the part. For this reason, such determinations can be carried out only in special laboratories and under conditions which do not usually agree with the conditions of actual use. What is required is a sensitive, fast method allowing the determination of wear under any operating conditions, without the necessity of stopping and disassembling the machine. The above mentioned requirements are the features that have made the Thin Layer Activation technique (TLA) the most widely used method applied in wear and corrosion studies in the last two decades. The TLA principle, taking in account that wear and corrosion processes are characterised by a loss of material, consists in an ion beam irradiation of a well defined volume of a machine part subjected to wear. The radioactivity level changes can usually be measured by gamma-ray spectroscopy methods. A review of both main TLA fields of application in major laboratories abroad and of those performed at the U-120 cyclotron of I.P.N.E.-Bucharest together with the existing trends to extend other nuclear analytical methods to tribological studies is presented as well.

  17. Quark effects in nuclear physics

    International Nuclear Information System (INIS)

    Scholten, O.

    1990-01-01

    The magnitude of the quark effect for low-energy nuclear physics is investigated. Coulomb energy is studied in the A=3 system in order to determine the effect of the composite structure of the nucleon. In the actual calculations a non-relativistic quark-cluster model description has been used. A nucleon size b=0.617 fm, the width of the relative wave function Φ of the quarks in the nucleon, has been assumed. It is concluded that the contribution to Coulomb energies due to quark effects are significant compared to the observed Nolen-Schiffer anomaly. However these do not provide the long searched for 'smoking gun'. When the free parameters that appear in the calculation are adjusted to reproduce the same charge form factor, the calculated anomalies are not significantly different. 2 figs., 2 tabs., 8 refs.2

    In the form of a tutorial addressed to non-specialists, the article provides an introduction to nuclear reactor technology and more specifically to Light Water Reactors (LWR); it also shows where materials and chemistry problems are encountered in reactor technology. The basics of reactor physics are reviewed, as well as the various strategies in reactor design and the corresponding choices of materials (fuel, coolant, structural materials, etc.). A brief description of the various types of commercial power reactors follows. The design of LWRs is discussed in greater detail; the properties of light water as coolant and moderator are put in perspective. The physicochemical and metallurgical properties of the materials impose thermal limits that determine the performance and the maximum power a reactor can deliver. (author)

    The increasing realization that the underlying mechanisms of nuclear physics are controlled by the inner quark structure of nucleons rather than the nucleons themselves is blurring the once fairly distinct frontier between nuclear and particle physics. Thus nuclear physicists are awaiting new high energy machines, notably CEBAF, the US Continuous Electron Beam Accelerator Facility now under construction in Newport News, Virginia, while particle physics facilities such as the LEAR low energy antiproton ring and the high energy muon beams at CERN are gaining popularity with the nuclear physics community

    about the importance of the Pauli exclusion principle and phase transitions in nuclear cluster models (Cseh and Hess) and an analysis of elastic scattering close to the Coulomb barrier in the framework of the optical model (Gómez-Camacho). Another important area is that of hadronic physics, the study of nucleons as composite systems of strongly interacting quarks and gluons. This field is situated on the borderline between nuclear and particle physics and presents a formidable challenge since the scale of the energies involved prohibits the use of the methods of perturbative QCD. In the session on hadronic physics, there were talks on chiral symmetry in non-perturbative QCD (Bietenholz), the structure of the nucleon in an unquenched quark model (Bijker), quark and meson degrees of freedom in Deeply Virtual Compton Scattering (Szczepaniak) and studies of hadronic structure by means of neutrino-induced pion production (Mariano). At ultrarelativistic energies, one can study the phase transition between hadronic matter and a new state of nuclear matter, the quark-gluon plasma. The Organizing Committee is proud to mention that the Cocoyoc 2010 meeting was one of first international conferences where the first scientific resuls from LHC were presented by the ALICE collaboration on proton-proton collisions at an energy of 900 GeV (Paic). In the session on cosmic rays, there was a talk on the origin of ultra high-energy cosmic rays (100 EeV = 1020 eV) as observed by the Pierre Auger Observatory (Medina-Tanco). Furthermore, there was a presentation of the project NuMoon which proposes to use the Moon's surface to detect cosmic rays that are out of the range of the Auger Observatory (Scholten). In addition, there was a review of the advances of the Mexican project HAWC, an observatory under construction in the Sierra Negra of Puebla (Sandoval) to study some of the most violentphenomena in the Universe through the detection of gamma rays with energies between hundreds of GeV and

    As the three-year period FY93-FY96 ended, there were six senior investigators on the grant full-time: Bulgac, Henley, Miller, Savage, van Kolck and Wilets. This represents an increase of two members from the previous three-year period, achieved with only a two percent increase over the budget for FY90-FY93. In addition, the permanent staff of the Institute for Nuclear Theory (George Bertsch, Wick Haxton, and David Kaplan) continued to be intimately associated with our physics research efforts. Aurel Bulgac joined the Group in September, 1993 as an assistant professor, with promotion requested by the Department and College of Arts and Sciences by September, 1997. Martin Savage, who was at Carnegie-Mellon University, jointed the Physics Department in September, 1996. U. van Kolck continued as research assistant professor, and we were supporting one postdoctoral research associate, Vesteinn Thorssen, who joined us in September, 1995. Seven graduate students were being supported by the Grant (Chuan-Tsung Chan, Michael Fosmire, William Hazelton, Jon Karakowski, Jeffrey Thompson, James Walden and Mitchell Watrous)

The participants comprised researchers from universities, industries and laboratories in the United States and Europe. In this volume are presented talks from that meeting on atomic and nuclear physics topics and on modern parallel processing concepts and hardware. The physics topics included strong fields in atomic and nuclear physics, the role of quarks in nuclear physics, the nuclear few-body problem, relativistic descriptions of heavy-ion collisions, nuclear hydrodynamics, Monte Carlo techniques for many-body problems, precision calculation of atomic QED effects, classical simulation of atomic processes, atomic structure, atomic many-body perturbation theory, quantal studies of small and large molecular systems, and multi-photon atomic and molecular problems

    It is really difficult to determine the exact date for the starting of nuclear physics research in Vietnam. Serious research on experimental nuclear physics began only since 1972 with the installation of such nuclear instrument like microtron accelerator, neutron generator, etc. During the past 20 years, hundred of research works have been published in local and foreign scientific journals. In the 5th national conference in Physics held in Hanoi in October 1993, at the Nuclear Physics section, 62 reports were presented reflecting the situation of nuclear physics research in the recent years, especially in the past five years. This review introduces its main results and formulates some perspectives of development in the late nineties in Vietnam. (K.A.). 27 refs., 4 figs., 6 tabs

    of neutrinos, such as double-beta decay and neutrino mixing were well represented at the conference. One of the central problems in modern cosmology and astrophysics is the search for dark matter. Several talks dealt with this subject and with methods to detect dark matter. Another intriguing and rather novel subject that was discussed at the meeting was time variation of fundamental physical constants. Two speakers have examined the sensitivity of Big-Bang Nucleosynthesis to the variation of the values of the fundamental constants. The role of some specific nuclei (such as Ni 56) in cosmology was pointed out. Many of the presentations at the conference described experimental studies of reactions relevant to nucleosynthesis at various stages of cosmic evolution. As reflected in the conference, these activities are widespread, encompassing many laboratories. Rare Isotope Beam (RIB) facilities are in the forefront of these studies. To understand the various processes of nucleosynthesis one has to have a good theory of nuclei far from the stability line. A number of presentations dealt with the description of such exotic nuclei. It is clear from the presentations that the future of experimental nuclear astrophysics looks promising as existing experimental facilities are being upgraded and new facilities are being built. X-Ray and Gamma-Ray Bursts and cosmic explosions were the subject of several talks. A discussion of various experiments attempting to measure time-reversal violation was the subject of one lecture. The solution of the puzzle as to why the universe is asymmetric with respect to matter-antimatter requires knowledge of the limit of time-reversal conservation. The late John Bahcall was a great astrophysicist and a supporter of the conference series 'Nuclear physics in Astrophysics'. On the last day of the conference, following a talk by Neta Bahcall from Princeton University on dark matter in the Universe, a short commemoration for John was held. Detailed

    As a result of the Chernobyl NPP accident considerable territories of Belarus have been contaminated with Pu and 2 41A m. The absence of instrumental techniques for a direct analysis of transuranium elements (TUE) in the objects of the environment has made the using of laborious radiochemical methods inevitable what, in its turn, has limited a necessary scale of investigations on TUE problem. The paper presents the more cheap and express instrumental nuclear and physical techniques for Pu and 2 41A m analysis in soils and near-ground layer of air having been developed at the Institute of Power Engineering Problems / National Academy of Sciences of Belarus (IPEP NASB), as well as some results having been obtained using these techniques

    There is no attempt with nuclear weapons to attack any places for terror or military victory since the atomic bombs dropped in Hiroshima and Nagasaki. People have obviously experienced horrible destructive power of nuclear weapons and continuously remembered a terrible tragedy, lots of organizations and experts express their concerns about the nuclear terrorism and try to interchange opinions for prevention of deadly weapons. The purpose of this paper is to provide the information of nuclear terrorism and what the potential risk of Republic of Korea is and how to do the efficient physical protection. Terror is from the old French terreur, which is derived from Latin verb terror meaning 'great fear'. This is a policy to suppress political opponents through using violence and repression. Many scholars have been proposed, there is no consensus definition of the term 'terrorism.' In 1988, a proposed academic consensus definition: 'Terrorism is an anxiety-inspiring method of repeated violent action, employed by (semi-) clandestine individual, group or state actors, for idiosyncratic, criminal or political reasons, whereby - in contrast to assassination - the direct targets of violence are not the main targets. The immediate human victims of violence are generally chosen randomly (targets of opportunity) or selectively (representative or symbolic targets) from a target population, and serve as message generators. These attacks showed that particular terrorists groups sought to cause heavy casualties and extreme terrorists were spontaneously prepared to make sacrifices for completion of that ultimate goal. Creation of nuclear weapons was like opening Pandora's box. Barack Obama has called nuclear terrorism 'the greatest danger we face'. Nuclear terror is one of the lethal risks. Using nuclear weapons or materials from terrorist groups is a fatal catastrophe to a targeting state though there is no accident similar like that. South

  6. The Physical Protection of Nuclear Material and Nuclear Facilities

    International Nuclear Information System (INIS)

    1999-08-01

    Physical protection against the theft or unauthorized diversion of nuclear materials and against the sabotage of nuclear facilities by individuals or groups has long been a matter of national and international concern. Although responsibility for establishing and operating a comprehensive physical protection system for nuclear materials and facilities within a State rests entirely with the Government of that State, it is not a matter of indifference to other States whether and to what extent that responsibility is fulfilled. Physical protection has therefore become a matter of international concern and co-operation. The need for international co-operation becomes evident in situations where the effectiveness of physical protection in one State depends on the taking by other States also of adequate measures to deter or defeat hostile actions against nuclear facilities and nuclear materials, particularly when such materials are transported across national frontiers

    1990-01-01

    Nuclear fusion reactions are attained by plasma gas phase reactions using magnetic fields and microwaves, and the degree of the reactions is controlled. That is, deuterium (D 2 ) is introduced into a plasma container by utilizing the resonance of microwaves capable of generating plasmas at high density higher by more than 10 - 10 3 times as compared with the high frequency and magnetic fields, and an electric energy is applied to convert gaseous D 2 into plasmas and nuclear fusion is conducted. Further, the deuterium ions in the plasmas are attracted to a surface of a material causing nuclear fusion under a negatively biased electric field from the outside (typically represented by Pd or Ti). Then, deuterium nuclei (d) or deuterium ions collide to the surface of the cathode on the side of palladium to conduct nuclear reaction at the surface or the inside (vicinity) thereof. However, a DC bias is applied as an external bias with the side of the palladium being negative. The cold nuclear fusion was demonstrated by placing a neutron counter in the vicinity of the container and confirming neutrons generated there. (I.S.)

    1988-08-01

    In April 1988 we, along with the nuclear theory groups of Brookhaven and MIT, submitted a proposal to the Department of Energy for a national Institute of Theoretical Nuclear Physics. The primary areas of investigation proposed for this Institute are: Strong Interaction Physics--including (1) The physics of hadrons, (2) QCD and the nucleus, (3) QCD at finite temperatures and high density; nuclear astrophysics; nuclear structure and nuclear many-body theory; and nuclear tests of fundamental interactions. It is, of course, no coincidence that these are the main areas of activity of the three groups involved in this proposal and of our group in particular. Here, we will organize an outline of the progress made at Stony Brook during the past year along these lines. These four areas do not cover all of the activities of our group

    Lentz, E.; Hix, W. R.; Baird, M. L.; Messer, O. E. B.; Mezzacappa, A.

    Core-collapse supernova models depend on the details of the nuclear and weak interaction physics inputs just as they depend on the details of the macroscopic physics (transport, hydrodynamics, etc.), numerical methods, and progenitors. We present preliminary results from our ongoing comparison studies of nuclear and weak interaction physics inputs to core collapse supernova models using the spherically-symmetric, general relativistic, neutrino radiation hydrodynamics code Agile-Boltztran. We focus on comparisons of the effects of the nuclear EoS and the effects of improving the opacities, particularly neutrino--nucleon interactions.

    2008-01-01

    As one of projects that were programmed in the cultivation program for human resources in nuclear engineering sponsored by the Ministry of Economy, Trade and Industry, the development of a virtual reactor for education of nuclear reactor physics started in 2007. The purpose of the virtual nuclear reactor is to make nuclear reactor physics easily understood with aid of visualization. In the first year of this project, the neutron slowing down process was visualized. The data needed for visualization are provided by Monte Carlo calculations; The flights of the respective neutrons generated by nuclear fissions are traced through a reactor core until they disappear by neutron absorption or slow down to a thermal energy. With this visualization and an attached supplement textbook, it is expected that the learners can learn more clearly the physical implication of neutron slowing process that is mathematically described by the Boltzmann neutron transport equation.

The abstracts of all contributions, plenary talks and posters were published in the Conference Handbook. The Symposium on Nuclear Physics has a long and distinguished history. From the beginning it was intended to be a relatively small meeting designed to bring together some of the leading nuclear scientists in the field. Its most distinctive feature is to provide a forum for specialists in different areas of nuclear physics, both theorists and experimentalists, students, postdocs and senior scientists, in a relaxed and informal environment providing them with a unique opportunity to exchange ideas. From the first meeting in Oaxtepec in 1978, the Symposium has been organized every year without interruption, which makes the present Symposium the 34th in a row. The scientific program consisted of 27 invited talks and 17 posters on a wide variety of hot topics in contemporary nuclear physics, ranging from the traditional fields of nuclear structure (Draayer, Pittel, Van Isacker, Fraser, Lerma, Cejnar, Hirsch, Stránský and Rath) and nuclear reactions (Aguilera, Gómez-Camacho, Scheid, Navrátil and Yennello) to radioactive beams (Padilla-Rodal and Galindo-Uribarri), nuclear astrophysics (Aprahamian, Civitarese and Escher), hadronic physics (Bijker, Valcarce and Hess), fundamental symmetries (Liu, Barrón-Palos and Baessler) and LHC physics (Menchaca-Rocha and Paic). The high quality of the talks, the prestige of the speakers and the broad spectrum of subjects covered in the meeting, shows that nuclear physics is a very active area at the frontier of scientific research which establishes bridges between many different disciplines.

    Full text: Neutron capture therapy (NCT) is developing method of swellings treatment, on which specialists set one's serious hopes, as at its realization the practical possibilities of the effect on any swellings open. The essence of method is simple and lies in the fact that to the swelling enter preparation containing boron or gadolinium, which one have a large capture cross-section of the thermal and slow neutrons. Then the swelling is irradiated once with the slow (epithermal) neutron beam with fluency about 10 9 neutrons /sm 2 s for a short time and single. As a result of thermal neutrons capture by the boron (or gadolinium) nuclei secondary radiation which affecting swelling cells is emitted. NCT of oncologic diseases makes the specific demands to physical parameters of neutron beams. Now research reactors are often used for NCT. However, research reactor WWR-SM (INP, Uzbekistan AS, Tashkent) doesn't provide with the epithermal neutron beams and to develop this technique the reactor, first of all, needs for obtaining the epithermal neutron beams with energy spectrum in range from 1 eV up to 10 keV and with intensity ∼ 10 9 neutron /sm 2 s. Practically it is connected with upgrade of at least one of existed reactor channels, namely with equipping with the special equipment (filters), forming from the reactor spectrum the beam of necessary energy neutrons. It requires realization of preliminary model calculations, including calculations of capture cross-sections, of filters types and their geometrical parameters on the basis of optimal selected materials. Such calculations, as a rule, are carried out on the basis of Monte-Carlo method and designed software for calculation of nuclear reactor physical and technical characteristics [1]. In this work the calculation results of devices variants and problems discussion, related with possibility of WWR-SM reactor using for NCT are presented. (author)

    A Technical Committee on Physical Protection of Nuclear Material met in April-May 1989 to advise on the need to update the recommendations contained in document INFCIRC/225/Rev.1 and on any changes considered to be necessary. The Technical Committee indicated a number of such changes, reflecting mainly: the international consensus established in respect of the Convention on the Physical Protection of Nuclear Material; the experience gained since 1977; and a wish to give equal treatment to protection against the theft of nuclear material and protection against the sabotage of nuclear facilities. The recommendations presented in this IAEA document reflect a broad consensus among Member States on the requirements which should be met by systems for the physical protection of nuclear materials and facilities. 1 tab

    2006-01-01

    The education and training of nuclear reactor operators is important to guarantee the safe operation of present and future nuclear reactors. Therefore, a course on basic 'Nuclear reactor physics' in the initial and continuous training of reactor operators has proven to be indispensable. In most countries, such training also results from the direct request from the safety authorities to assure the high level of competence of the staff in nuclear reactors. The aim of the basic course on 'Nuclear Reactor Physics for reactor operators' is to provide the reactor operators with a basic understanding of the main concepts relevant to nuclear reactors. Seen the education level of the participants, mathematical derivations are simplified and reduced to a minimum, but not completely eliminated

  14. Physical protection nuclear facilities against sabotage

    defined by 'Security Categories'. This method of categorization took into account the attractiveness of the nuclear material for unauthorized removal and the potential radiological consequences of an act of sabotage against the material directly or against the facility where the material is used or processed. Category I nuclear material and nuclear power plants were assigned to the 'Security Category' which required the highest level of physical protection. This level was defined by required measures in a 'Security Measure Catalogue'. These requirements were based on a certain model of potential adversaries, the DBT. Having the DBT translated into a number of requirements it was a so called compliance based approach. This system was changed because this approach lacked of flexibility and did not fit with categorization table in the CPPNM. The catalogue system was replaced by guidelines considering the actual main nuclear activities in Germany which are the operation of light water NPPs and transport of fresh and spent fuel. In the guideline for the physical protection of NPPs with light water reactors based on a safety analysis a specific objective is defined which requires the protection of certain functions concerning cooling, power supply and integrity. The way how to protect these functions and on which level is a result of the application of the DBT. An attempt of sabotage might be successful by a destruction of certain vital equipment only. In this hypothetical case only the consequences of a sabotage can be mitigated. That is one of the important differences to the protection against unauthorized removal of material. In order to give the response forces a realistic chance to terminate an attempt of sabotage in time which might be performed by outsiders the measures of prevention and delay - that means on site measures - become of more importance. Concerning the protection against malevolent acts by an individual from inside a facility the number of interfaces to

  16. 1932: ''annus mirabilis'' for nuclear physics

    International Nuclear Information System (INIS)

    Hughes, J.

    1998-01-01

    1932 was an extraordinary year for nuclear physics: J. Chadwick discovered the neutron, C.D.Anderson identified the positron and the first artificial disintegration was realised with a particle accelerator by J.Cockcroft and E.Walton. These 3 discoveries transformed nuclear physics by providing basis on which any new research could be led. The neutron allowed the discovery of artificial radioactivity by Joliot-Curie in 1934 and later the discovery of nuclear fission by O. Hahn, F. Strassman and L. Meitner. The positron brought new concepts about cosmic radiation and drew the way to the discovery of new particles. Artificial disintegration paved the way to the ever-bigger machines. It was the beginning of the era of breaking nuclei. 1932 deserves its title of ''annus mirabilis'' of physics. This article presents the quick evolution of ideas, concepts in nuclear physics in the thirties. (A.C.)

    International Nuclear Information System (INIS)

    1993-01-01

    Physical protection against the theft or unauthorized diversion of nuclear materials and against the sabotage of nuclear facilities by individuals or groups has long been a matter of national and international concern. Although responsibility for establishing and operating a comprehensive physical protection system for nuclear materials and facilities within a State rests entirely with the Government of that State, it is not a matter of indifference to other States whether and to what extent that responsibility is fulfilled. Physical protection has therefore become a matter of international concern and co-operation. The need for international cooperation becomes evident in situations where the effectiveness of physical protection in one State depends on the taking by other States also of adequate measures to deter or defeat hostile actions against nuclear facilities and materials, particularly when such materials are transported across national frontiers

    1989-01-01

    The undergraduate program in nuclear engineering at the University of Cincinnati provides three-quarters of nuclear reactor theory that concentrate on physical principles, with calculations limited to those that can be conveniently completed on programmable calculators. An additional one-quarter course is designed to introduce the student to realistic core physics calculational methods, which necessarily requires a computer. Such calculations can be conveniently demonstrated and completed with the modern microcomputer. The one-quarter reactor computations course includes a one-group, one-dimensional diffusion code to introduce the concepts of inner and outer iterations, a cell spectrum code based on integral transport theory to generate cell-homogenized few-group cross sections, and a multigroup diffusion code to determine multiplication factors and power distributions in one-dimensional systems. Problem assignments include the determination of multiplication factors and flux distributions for typical pressurized water reactor (PWR) cores under various operating conditions, such as cold clean, hot clean, hot clean at full power, hot full power with xenon and samarium, and a boron concentration search. Moderator and Doppler coefficients can also be evaluated and examined

    1983-01-01

    The report is in two parts. The first part reviews the current understanding of nuclear physics and indicates areas of significant interest for future work. It briefly discusses the special contributions of nuclear physics in other sciences. The second part considers new facilities which would be particularly relevant to the future development of nuclear physics in the UK. The present position of UK nuclear physics with respect to the wider nuclear community is considered. In conclusion the report establishes priorities for UK nuclear physics and makes recommendations for future action for the provision of facilities and also for future funding and manpower levels. The working party seeks to build on the valuable base provided by the NSF and Oxford accelerators. The principal recommendation of the Working Party is that a new 600MeV continuous beam electron accelerator should be built at the Daresbury Laboratory. For higher energy heavy ion beams the Working Party suggests these should be sought at overseas laboratories. (author)

    The use of edge enhancement and computer motion display improves the detection of regional wall motion abnormalities in the LV. Improved gating and processing techniques should improve the accuracy of ventricular volume vs time measurements. It is hoped that the simulations described will aid in the development of new instrumentation for the collection and analysis of nuclear ventriculographie data

  12. Nuclear physics at small distances

    Indian Academy of Sciences (India)

    We report on the study of meson and resonance production in nuclear collisions near the threshold. Because of the large momentum transfer, these reactions occur at length scales less than the size of the hadrons. We explore whether they are best described in terms of the quark–gluon picture or the meson-exchange ...

  15. QCD sum rules and applications to nuclear physics

    International Nuclear Information System (INIS)

    Cohen, T.D.; Xuemin, J.

    1994-12-01

    Applications of QCD sum-rule methods to the physics of nuclei are reviewed, with an emphasis on calculations of baryon self-energies in infinite nuclear matter. The sum-rule approach relates spectral properties of hadrons propagating in the finite-density medium, such as optical potentials for quasinucleons, to matrix elements of QCD composite operators (condensates). The vacuum formalism for QCD sum rules is generalized to finite density, and the strategy and implementation of the approach is discussed. Predictions for baryon self-energies are compared to those suggested by relativistic nuclear physics phenomenology. Sum rules for vector mesons in dense nuclear matter are also considered. (author)

    2007-12-01

    This Report is a result of the Polish Nuclear Physics Network (PNPN) action having as objective the mapping study of the basic and applied research in this domain in Poland. In the often employed slang it constitutes one of the '' deliverables '' of the EWON (East-West Outreach) Network, operating within the I3- (Integrated Infrastructure Initiative) EURONS, one of the Nuclear Physics projects in the Six Framework Programme (FP6). However, although prepared within the nuclear structure EURONS framework, this mapping study also reports on the activities in the hadron physics in Poland (organized in the FP6 within a second Nuclear Physics project I3-Hadron Physics) as well as in Nuclear Theory and Applications of Nuclear Physics. The Report contains references to activities and published papers from the last ten years: 1996 - 2006. In some cases also slightly older data are included, if necessary, for the completeness of the reported subjects. The Report is organized as follows. After the information on Polish Nuclear Physics Network (a part of the EWON Network), a few overview papers describe the main domains of the PNPN scientific activity. The contents of these papers were previously presented during the NuPECC meeting, held in Krakow June 9, 2006. A number (89) of more detailed contributions (together with appropriate references) emanating from various research groups follows the review articles. Some of the contributions provide concise summaries of wide research activities. Other authors preferred to report separately or individually on narrower topics. Most of the presented activities were conducted within the international collaborations. However, the adopted policy was that only Polish researchers are indicated as authors of the contributions, whereas the international collaborations are reflected by (all) authors of cited publications. The Polish Nuclear Physics Long-Range Plan prepared recently by the Nuclear Physics Committee of the National Atomic Energy

  19. Fast breeder physics and nuclear core design

    International Nuclear Information System (INIS)

    Marth, W.; Schroeder, R.

    1983-07-01

    This report gathers the papers that have been presented on January 18/19, 1983 at a seminar ''Fast breeder physics and nuclear core design'' held at KfK. These papers cover the results obtained within about the last five years in the r+d program and give some indication, what still has to be done. To begin with, the ''tools'' of the core designer, i.e. nuclear data and neutronics codes are covered in a comprehensive way, the seminar emphasized the applications, however. First of all the accuracies obtained for the most important parameters are presented for the design of homogeneous and heterogeneous cores of about 1000 MWe, they are based on the results of critical experiments. This is followed by a survey on activities related to the KNK II reactor, i.e. calculations concerning a modification of the core as well as critical experiments done with respect to re-loads. Finally, work concerning reactivity worths of accident configurations is presented: the generation of reactivity worths for the input of safety-related calculations of a SNR 2 design, and critical experiments to investigate the requirements for the codes to be used for these calculations. These papers are accompanied by two contributions from the industrial partners. The first one deals with the requirements to nuclear design methods as seen by the reactor designer and then shows what has been achieved. The latter one presents state, trends, and methods of the SNR 2 design. The concluding remarks compare the state of the art reached within DeBeNe with international achievements. (orig.) [de

  20. Physical security of nuclear facilities

    International Nuclear Information System (INIS)

    Dixon, H.

    1987-01-01

    A serious problem with present security systems at nuclear facilities is that the threats and standards prepared by the NRC and DOE are general, and the field offices are required to develop their own local threats and, on that basis, to prepared detailed specifications for security systems at sites in their jurisdiction. As a result, the capabilities of the systems vary across facilities. Five steps in particular are strongly recommended as corrective measures: 1. Those agencies responsible for civil nuclear facilities should jointly prepare detailed threat definitions, operational requirements, and equipment specifications to protect generic nuclear facilities, and these matters should be issued as policy. The agencies should provide sufficient detail to guide the design of specific security systems and to identify candidate components. 2. The DOE, NRC, and DOD should explain to Congress why government-developed security and other military equipment are not used to upgrade existing security systems and to stock future ones. 3. Each DOE and NRC facility should be assessed to determine the impact on the size of the guard force and on warning time when personnel-detecting radars and ground point sensors are installed. 4. All security guards and technicians should be investigated for the highest security clearance, with reinvestigations every four years. 5. The processes and vehicles used in intrafacility transport of nuclear materials should be evaluated against a range of threats and attack scenarios, including violent air and vehicle assaults. All of these recommendations are feasible and cost-effective. The appropriate congressional subcommittees should direct that they be implemented as soon as possible

  1. Probabilistic methods for physics

    International Nuclear Information System (INIS)

    Cirier, G

    2013-01-01

    We present an asymptotic method giving a probability of presence of the iterated spots of R d by a polynomial function f. We use the well-known Perron Frobenius operator (PF) that lets certain sets and measure invariant by f. Probabilistic solutions can exist for the deterministic iteration. If the theoretical result is already known, here we quantify these probabilities. This approach seems interesting to use for computing situations when the deterministic methods don't run. Among the examined applications, are asymptotic solutions of Lorenz, Navier-Stokes or Hamilton's equations. In this approach, linearity induces many difficult problems, all of whom we have not yet resolved.

  2. Nuclear physics accelerator facilities of the world

    International Nuclear Information System (INIS)

    1991-12-01

    this report is intended to provide a convenient summary of the world's major nuclear physics accelerator facility with emphasis on those facilities supported by the US Department of Energy (DOE). Previous editions of this report have contained only DOE facilities. However, as the extent of global collaborations in nuclear physics grows, gathering summary information on the world's nuclear physics accelerator facilities in one place is useful. Therefore, the present report adds facilities operated by the National Science Foundation (NSF) as well as the leading foreign facilities, with emphasis on foreign facilities that have significant outside user programs. The principal motivation for building and operating these facilities is, of course, basic research in nuclear physics. The scientific objectives for this research were recently reviewed by the DOE/NSF Nuclear Science Advisory Committee, who developed a long range plan, Nuclei, Nucleons, and Quarks -- Nuclear Science in the 1990's. Their report begins as follows: The central thrust of nuclear science is the study of strongly interacting matter and of the forces that govern its structure and dynamics; this agenda ranges from large- scale collective nuclear behavior through the motions of individual nucleons and mesons, atomic nuclei, to the underlying distribution of quarks and gluons. It extends to conditions at the extremes of temperature and density which are of significance to astrophysics and cosmology and are conducive to the creation of new forms of strongly interacting matter; and another important focus is on the study of the electroweak force, which plays an important role in nuclear stability, and on precision tests of fundamental interactions. The present report provides brief descriptions of the accelerator facilities available for carrying out this agenda and their research programs

  3. Physical protection of nuclear installations

    Toepfer, K.

    1989-01-01

    This contribution investigates the possible danger and the legal basis of physical protection and explains the current, integrated system provided for, as well as the underlying possible scenarios of an assault: (1) by a violent crowd of aggressors outside the installation, (2) by a small group of aggressors outside the installation, (3) by a person allowed to enter (internal assault). The physical protection system supplements the internal safety measures to enhance protection against hypothetical and possible acts of terrorism or other criminal assault. The system covers external and internal controlled areas, access monitoring, physical protection control room and service, security checks of the personnel, and activities to disclose sabotage. Some reflections on the problem field between security controls and the constitutional state conclude this contribution. (orig./HSCH) [de

  4. The method of sections in molecular physics

    International Nuclear Information System (INIS)

    Natarajan, P.; Zygelman, B.

    1993-01-01

    In the standard Born-Oppenheimer theory the nuclear wave-function for a bound, rotating, di-atom system is described by the Wigner functions. Unlike the spherical harmonics, the Wigner functions exhibit cusp singularities at the poles of the space-fixed coordinate system. These singularities are identical to the ones encountered in the quantum mechanics treatment of a charged particle under the influence of a magnetic monopole. In the latter case the method of sectional was introduced to eliminate the singularities. The method of sections was also introduced in molecular physics. We discuss here, in detail, their properties and advantage of using this construction in molecular physics

    1999-06-01

    The latest review (1993) of this document was of limited scope and resulted in changes to the text of INFCIRC/225/Rev.2 designed to make the categorization table in that document consistent with the categorization table contained in the Convention on Physical Protection of Nuclear Materials. Consequently, a comprehensive review of INFCIRC/225 has not been conducted since 1989. Consequently, a meeting of national experts was convened from 2-5 June 1998 and from 27-29 October 1998 for a thorough review of INFCIRC/225/Rev.3. The revised document reflects the recommendations of the national experts to improve the structure and clarity of the document and to take account of improved technology and current international and national practices. In particular, a chapter has been added which provides specific recommendations related to sabotage of nuclear facilities and nuclear material. As a result of this addition, the title has been changed to 'The Physical Protection of Nuclear Material and Nuclear Facilities'. The recommendations presented in this IAEA document reflect a broad consensus among Member States on the requirements which should be met by systems for the physical protection of nuclear materials and facilities. It is hoped that they will provide helpful guidance for Member States.

    Due to its achievements, nuclear physics is more and more present in life of every member of the society. Its applications in the medical field and in nuclear energy, as well as the advanced research, always pushing the limits of science towards micro cosmos and macro cosmos, are subjects frequently presented in the media. In addition to their invaluable benefits, these achievements involve also particular rules to prevent potential risks. These risks are also underlined by the media, often being presented in an unfriendly manner. Specialists in nuclear physics are familiar with these problems complying with the specific rules in order to reduce risks at insignificant levels. The development of a specific field ('Radiation protection') defining norms and requirements for 'assuring the radiological safety of the workers, population and environment', and its dynamics represent a proof of a responsible attitude regarding nuclear safety. Dedicated international bodies and experts analyze and rigorously evaluate risks in order to draw the right ways of managing activity in the field. The improvement of the formal and informal education of public regarding the real risks of nuclear applications is very important in order to understand and better assimilate some general rules concerning the use of these techniques, as well as for their correct perception, leading to an increase of interest towards nuclear physics. This educational update can be started even from elementary school and continued in each stage of formal education in adapted forms. The task of informing general public is to be carried out mainly by specialists who, unlike 30-40 years ago, can rely on a much more efficient generation of communications' mean. Taking into account the lack of interest for nuclear, an attractive way of presenting the achievements and future possibilities of nuclear physics would contribute to youth orientation towards specific universities in order to become next generation of

    2003-04-01

    The experimental Nuclear Physics activity of the Italian researchers is briefly reviewed. The experiments, that are financially supported by the INFN, are done in strict collaboration by more than 500 INFN and University researchers. The experiments cover all the most important field of the modern Nuclear Physics with probes extremely different in energy and interactions. Researches are done in all the four National Laboratories of the INFN even if there is a deeper involvement of the two national laboratories expressly dedicated to Nuclear Physics: the LNL (Laboratorio Nazionale di Legnaro) and LNS (Laboratorio Nazionale del Sud) where nuclear spectroscopy and reaction dynamics are investigated. All the activities with electromagnetic probes develops in abroad laboratories as TJNAF, DESY, MAMI, ESFR and are dedicated to the studies of the spin physics and of the nucleon resonance; hypernuclear and kaon physics is investigated at LNF. A strong community of researchers work in the relativistic and ultra-relativistic heavy ions field in particular at CERN with the SPS Pb beam and in the construction of the ALICE detector for heavy-ion physics at the LHC collider. Experiments of astrophysical interest are done with ions of very low energy; in particular the LUNA accelerator facility at LNGS (Laboratorio Nazionale del Gran Sasso) succeeded measuring cross section at solar energies, below or near the solar Gamow peak. Interdisciplinary researches on anti-hydrogen atom spectroscopy and on measurements of neutron cross sections of interest for ADS development are also supported.

    1988-09-01

    With the advent of the standard model of quarks, leptons and unified forces one has achieved an understanding of the wealth of data in particle physics and provided a new basis for the understanding of nuclei and hadrons. In particle physics one now seeks to improve the standard model and to go beyond it. In nuclear physics one enquires about the role of quarks and gluons in the dynamics of strongly interacting systems. To answer these new questions an impressive network of large accelerator facilities, including CEBAF, is under construction or in the proposal stage. A global view of this network and its physics is given. (Author) (3 figs.)

    International Nuclear Information System (INIS)

    Dover, C.B.

    1988-01-01

    Recent progress in the understanding of strange particle interactions with nuclear systems is reviewed. We discuss the relative merits of various reactions such as (K - , π/sup +-/), (π + , K + ), or (γ, K + ) for hypernuclear production. The structure of /sub Λ/ 13 C is analyzed in some detail, in order to illustrate the role of the ΛN residual interaction and approximate dynamical symmetries in hypernuclear structure. Recent results on the single particle states of a Λ in heavy systems, as revealed by (π + , K + ) reaction studies, are used to extract information on the density dependence and effective mass which characterize the Λ-nucleus mean field. Finally, we develop the idea the K + -nucleus scattering at low energies is sensitive to the subtle ''swelling'' effects for nucleons bound in nuclei. 64 refs., 13 figs

    Teaching of science subjects, specifically physics among others, is important in Hungarian schools. The paper starts with some historical aspects on how the modern physics reached Hungarian schools, what kinds of methods the physics teachers use for their in-service training and what is their success. In 1985 Hungarian Government introduced the system of physics teacher's in-service training for a year. The courses end with a thesis and examination. Teachers have a possibility to join the nuclear physics intensive course of Nuclear Physics Department at Eottvos University. Curriculum and topics of laboratory practice are given together with some dissertations of the course. Moreover, several competition (Leo Szilard competition) is mentioned with starting that in each year the 5 best students get free entrance to the Hungarian universities. (S. Ohno)

    One of the highlights of the summer was the International Conference on Nuclear Physics, held at Berkeley in August. These big meetings provide a periodic focus for the nuclear physics community. Overall, the Conference paid a lot of attention to topics and phenomna which only a few years ago would have been considered exotic. With many novel ideas being put forward and with new projects afoot, a lot of fresh ground could have been covered by the time of the next meeting, scheduled to be held in Florence in a few years

    2016-11-01

    One of the difficulties in modern physics teaching is the limited availability of experimental activities. This is particularly true for teaching nuclear physics in high school or college. The activities suggested in the literature generally symbolise real phenomenon, using simulations. It happens because the experimental practices mostly include some kind of expensive radiation detector and an ionising radiation source that requires special care for handling and storage, being subject to a highly bureaucratic regulation in some countries. This study overcomes these difficulties and proposes three nuclear physics experiments using a low-cost ion chamber which construction is explained: the measurement of 222Rn progeny collected from the indoor air; the measurement of the range of alpha particles emitted by the 232Th progeny, present in lantern mantles and in thoriated welding rods, and by the air filter containing 222Rn progeny; and the measurement of 220Rn half-life collected from the emanation of the lantern mantles. This paper presents the experimental procedures and the expected results, indicating that the experiments may provide support for nuclear physics classes. These practices may outreach wide access to either college or high-school didactic laboratories, and the apparatus has the potential for the development of new teaching activities for nuclear physics.

    2012-05-01

    This volume contains the lectures and short talks given at the XIX International School on Nuclear Physics, Neutron Physics and Applications. The School was held from 19-25 September 2011 in 'Club Hotel Bolero' located in the 'Golden Sands' (Zlatni Pyasaci) Resort Complex on the Black Sea coast, near Varna, Bulgaria. The School was organized by the Institute for Nuclear Research and Nuclear Energy of the Bulgarian Academy of Sciences. The co-organizer of the School was the Bulgarian Nuclear Regulatory Agency and the Bogoliubov Laboratory of Theoretical Physics of the Joint Institute for Nuclear Research - Dubna.

    2012-01-01

    This statistics textbook, with particular emphasis on radiation protection and dosimetry, deals with statistical solutions to problems inherent in health physics measurements and decision making. The authors begin with a description of our current understanding of the statistical nature of physical processes at the atomic level, including radioactive decay and interactions of radiation with matter. Examples are taken from problems encountered in health physics, and the material is presented such that health physicists and most other nuclear professionals will more readily understand the application of statistical principles in the familiar context of the examples. Problems are presented at the end of each chapter, with solutions to selected problems provided online. In addition, numerous worked examples are included throughout the text.

  20. Main Achievements 2003-2004 - Nuclear Physics

    International Nuclear Information System (INIS)

    2005-01-01

    Two Departments of our Institute are engaged in nuclear studies, in the following areas: studies of the nuclear reaction mechanism at low, intermediate and high energies, studies of nuclear structure by means of gamma spectroscopy, and theoretical research concerning nuclear structure and reaction mechanisms. Most of these studies are carried out in the form of international collaborations with the world-leading nuclear physics experimental facilities. Our physicists usually play an important role in these collaborative projects and often lead them. Nuclear structure experiments were performed mainly within the following European Large Scale Facilities: ALPI-INFN-Legnaro, VIVITRONIReS-Strasbourg, UNILAC/SIS-GSI-Darmstadt, K100-Cyclotron-Jyvaeskylea with the use of the GASP, GARFIELD, EUROBALL, ICARE, RISING + FRS, RITU+JUROGAM systems and with the application of RFD, HECTOR, DIAMANT, EUCLIDES ancillary detectors. Experimental data were also obtained at the Argonne National Laboratory, USA, with the GAMMASPHERE array and the ATLAS accelerator. In addition, we are involved in planning the experiments for the project of international accelerator facility of the next generation FAIR (Facility for Antiproton and Ion Research) at GSI. The nuclear reaction experiments were performed at the Joint Institute of Nuclear Physics in Dubna (collaborations FASA and COMBAS), in GANIL in Caen, in the Forschungszentrum Juelich at the accelerator COSY in the framework of collaboration PISA, as well as at the Warsaw Laboratory of Heavy Ions. The hadronic nuclear physics experiments were carried out exclusively at the Forschungszentrum Juelich where we have participated in international collaborations COSY11, GEM and HIRES. Recently, we have joined international detector project WASA planned at Forschungszentrum Juelich and plan to participate in the project PANDA, being constructed in GSI Darmstadt. Both detectors will be devoted to low and intermediate hadronic physics. We also

    Method of Monte Carlo integration is reviewed briefly and some of its applications in physics are explained. A numerical experiment on random generators used in the monte Carlo techniques is carried out to show the behavior of the randomness of various methods in generating them. To account for the weight function involved in the Monte Carlo, the metropolis method is used. From the results of the experiment, one can see that there is no regular patterns of the numbers generated, showing that the program generators are reasonably good, while the experimental results, shows a statistical distribution obeying statistical distribution law. Further some applications of the Monte Carlo methods in physics are given. The choice of physical problems are such that the models have available solutions either in exact or approximate values, in which comparisons can be mode, with the calculations using the Monte Carlo method. Comparison show that for the models to be considered, good agreement have been obtained

    The technologies used in nuclear medicine for diagnostic imaging have evolved over the last century, starting with Röntgen’s discovery of X rays and Becquerel’s discovery of natural radioactivity. Each decade has brought innovation in the form of new equipment, techniques, radiopharmaceuticals, advances in radionuclide production and, ultimately, better patient care. All such technologies have been developed and can only be practised safely with a clear understanding of the behaviour and principles of radiation sources and radiation detection. These central concepts of basic radiation physics and nuclear physics are described in this chapter and should provide the requisite knowledge for a more in depth understanding of the modern nuclear medicine technology discussed in subsequent chapters.

  3. PREFACE: XXXV Symposium on Nuclear Physics

    2012-09-01

    Conference logo The XXXV Symposium on Nuclear Physics was held at Hotel Hacienda Cocoyoc, Morelos, Mexico from January 3-6 2012. Conceived in 1978 as a small meeting, over the years and thanks to the efforts of various organizing committees, the symposium has become a well known international conference on nuclear physics. To the best of our knowledge, the Mexican Symposium on Nuclear Physics represents the conference series with longest tradition in Latin America and one of the longest-running annual nuclear physics conferences in the world. The Symposium brings together leading scientists from all around the world, working in the fields of nuclear structure, nuclear reactions, physics with radioactive ion beams, hadronic physics, nuclear astrophysics, neutron physics and relativistic heavy-ion physics. Its main goal is to provide a relaxed environment where the exchange of ideas, discussion of new results and consolidation of scientific collaboration are encouraged. To celebrate the 35th edition of the symposium 53 colleagues attended from diverse countries including: Argentina, Australia, Canada, Japan, Saudi Arabia and USA. We were happy to have the active participation of Eli F Aguilera, Eduardo Andrade, Octavio Castaños, Alfonso Mondragón, Stuart Pittel and Andrés Sandoval who also participated in the first edition of the Symposium back in 1978. We were joined by old friends of Cocoyoc (Stuart Pittel, Osvaldo Civitarese, Piet Van Isacker, Jerry Draayer and Alfredo Galindo-Uribarri) as well as several first time visitors that we hope will come back to this scientific meeting in the forthcoming years. The scientific program consisted of 33 invited talks, proposed by the international advisory committee, which nicely covered the topics of the Symposium giving a balanced perspective between the experimental and the theoretical work that is currently underway in each line of research. Fifteen posters complemented the scientific sessions giving the opportunity

    The UMass group has concentrated on using electromagnetic probes, particularly the electron in high-energy scattering experiments at the Stanford Liner Accelerator Center (SLAC). Plans are also being made for high energy work at the Continuous Beam Accelerator Facility (CEBAF). The properties of this accelerator should permit a whole new class of coincidence experiments to be carried out. At SLAC UMass has made major contributions toward the plans for a cluster-jet gas target and detector system at the 16 GeV PEP storage ring. For the future CEBAF accelerator, tests were made of the feasibility of operating wire drift chambers in the vicinity of a continuous electron beam at the University Illinois microtron. At the same time a program of studies of the nuclear structure of more complex nuclei has been continued at the MIT-Bates Linear Accelerator Center and in Amsterdam at the NIKHEF-K laboratory. At the MIT-Bates Accelerator, because of an unforeseen change in beam scheduling as a result of problems with the T 20 experiment, the UMass group was able to complete data acquisition on experiments involving 180 degrees elastic magnetic scattering on 117 Sn and 41 Ca. A considerable effort has been given to preparations for a future experiment at Bates involving the high-resolution threshold electrodisintegration of the deuteron. The use of these chambers should permit a high degree of discrimination against background events in the measurement of the almost neutrino-like small cross sections that are expected. In Amsterdam at the NIKHEF-K facility, single arm (e,e') measurements were made in November of 1987 on 10 B in order to better determine the p 3/2 wave function from the transition from the J pi = 3 + ground state to the O + excited state at 1.74 MeV. In 1988, (e,e'p) coincidence measurements on 10 B were completed. The objective was to obtain information on the p 3/2 wave function by another means

  6. Stochastic Effects; Application in Nuclear Physics

    2000-04-01

    Stochastic effects in nuclear physics refer to the study of the dynamics of nuclear systems evolving under stochastic equations of motion. In this dissertation we restrict our attention to classical scattering models. We begin with introduction of the model of nuclear dynamics and deterministic equations of evolution. We apply a Langevin approach - an additional property of the model, which reflect the statistical nature of low energy nuclear behaviour. We than concentrate our attention on the problem of calculating tails of distribution functions, which actually is the problem of calculating probabilities of rare outcomes. Two general strategies are proposed. Result and discussion follow. Finally in the appendix we consider stochastic effects in nonequilibrium systems. A few exactly solvable models are presented. For one model we show explicitly that stochastic behaviour in a microscopic description can lead to ordered collective effects on the macroscopic scale. Two others are solved to confirm the predictions of the fluctuation theorem. (author)

    Nuclear data processing for reactor physics calculation has been done. Raw nuclear data cross-sections on file ENDF should be prepared and processed before it used in neutronic calculation. The processing code system such as NJOY-PC code has been used from linearization of nuclear cross-sections data and background contribution of resonance parameter (MF2) using RECONR module (0K) with energy range from 10 -5 to 10 7 eV. Afterward, the neutron cross-sections data should be processed and broadened to desire temperature (i.e. 293K) by using BROADR module. The Grouper and Therma modules will be applied for multi-groups calculation which suitable for WIMS/D4 (69 groups) and thermalization of nuclear constants. The final stage of processing nuclear cross-sections is updating WIMS/D4 library. The WIMSR module in NJOY-PC and WILLIE code will be applied in this stage. The evaluated nuclear data file, especially for 1 H 1 isotope, was taken from JENDL-3.2 and ENDF/B-VI for preliminary study. The results of nuclear data processing 1 H 1 shows that the old-WIMS (WIMS-lama) library have much discrepancies comparing with JENDL-3.2 or ENDF/B-VI files, especially in energy around 5 keV

    Braye, F.

    1994-07-01

    Substitution of tissue or human organ by biomaterials represents a problem, really hard, but which importance and interest justify all the efforts devoted which must also require a range of skills. In this work, we studied two produces of osseous substitution. One, the Coral, is a natural produce which interest, for such use, has been demonstrated in previous work executed in the bosom of our team. The other, the Hydroxyapatite, is a synthetic produce. Its presence in the form of micro crystal in human skeleton justifies its use for such purpose. Just after sterilization, natural Coral and synthetic Hydroxyapatite have been implanted in the femurs of sheep. Regularly, we used to extract the implants from the femurs to study the kinetics of elementary mineral transformation of both the osseous substitutes. For the first time and thanks to the PIXE Method (Particles Induced X-ray Emission), we had measured after implantation at different intervals all alone a cross section, the concentrations of mineral produces. The breakdown according to mineral elements (Ca, P, Sr, Zn, Fe) in the implant, in the receiver site and also at the interface, permitted to show that Kinetics of Coral resorption was faster than the one of Hydroxylapatite; in the same way, the osseous attack was not global but, on the contrary, centripetal. Concurrently, in accordance with time of implantation by spectrometry with atomic emission and inductive coupling, measurements of total concentrations proved the results of analyse through PIXE Method about kinetics of implant's resorption. Moreover, measurements by diffraction of X-rays and by neutronic radioactivation with thermal neutrons permitted respectively to make a satisfactory crystallographic verification of the specimens before and after sterilization. Finally, thanks to those measurements, it was possible to check if no potential contamination, caused by treatment or even by making of implants, was detected. (author). 49 refs., 35 tabs., 85

  16. Assessment of physical protection systems: EVA method

    International Nuclear Information System (INIS)

    Bernard, J.-L.; Lamotte, C.; Jorda, A.

    2001-01-01

    CEA's missions in various sectors of activity such as nuclear, defence, industrial contracts and the associated regulatory requirements, make it necessary to develop a strategy in the field of physical protection. In particular, firms having nuclear materials are subject to the July 25, 1980 law no.80-572 on the protection and control of nuclear materials. A holding permit delivered by the regulatory authority is conditioned to the protection by the operator of the nuclear materials used. In France it is the nuclear operator who must demonstrate, in the form of a security study, that potential aggressors would be neutralised before they could escape with the material. To meet these requirements, we have developed methods to assess the vulnerability of our facilities. The EVA method, the French acronym for 'Evaluation de la vulnerabilite des Acces' (access vulnerability system) allows dealing with internal and external threats involving brutal actions. In scenarios relating to external threat, the intruders get past the various barriers of our protection system, attempting to steal a large volume of material in one swoop and then escape. In the case of internal threat, the goal is the same. However, as the intruder usually has access to the material in the scope of his activities, the action begins at the level of the target. Our protection system is based on in-depth defense where the intruders are detected and then delayed in their advance towards their target to allow time for intervention forces to intercept them

  17. Why should we study nuclear physics?

    After a brief look at the history of nuclear science and technology in the past hundred years, arguments are given for the study of Nuclear Physics, very different of course from what they were in the middle of the past century. Nuclear physics no longer appears as a good bet to study the strong force. Problems left open by QCD are better addressed by relativistic ion accelerators, RHIC and LHC/Alice. Radioactive Ion Beams have caused a renaissance of experimental nuclear physics. They explore the nuclear equation of state far from the stability valley, discovering new isotopes and new forms of dynamics, such as halo nuclei. They contribute essential data to nuclear astrophysics. They have new applications in medicine and industry. They enjoy strong support all around the world; in Asia, Japan is a leader and Korea and China are joining the club. Nuclear processes are ubiquitous in astrophysics: Big bang nucleosynthesis, Main Sequence stars, evolved stars (Asymptotic Giant Branch and Supernovae). Understanding what is going on requires knowledge from laboratory measurements; at the same time astrophysics gives nuclear physics a laboratory having no equivalent on Earth. Applications of nuclear physics pervade modern societies. Medicine and material sciences, make ample use of radioactive sources and ion beams, as do all branches of agriculture and industry. Accelerators are now commercially available and part of the industrial landscape. Implications on training competent scientists, technicians and engineers are enormous. Particularly crucial are matters of safety. Nuclear Power Plants are a major element of the Vietnamese energy policy in the decades to come. Their safe and efficient operation requires high level skills and competence that cover a broad spectrum of scientific and technical, but also socio-economic and geo-political issues. Nuclear physics must be taught to the young generation in a form that takes proper account of the current scientific

  18. Level densities in nuclear physics

    International Nuclear Information System (INIS)

    Beckerman, M.

    1978-01-01

    In the independent-particle model nucleons move independently in a central potential. There is a well-defined set of single- particle orbitals, each nucleon occupies one of these orbitals subject to Fermi statistics, and the total energy of the nucleus is equal to the sum of the energies of the individual nucleons. The basic question is the range of validity of this Fermi gas description and, in particular, the roles of the residual interactions and collective modes. A detailed examination of experimental level densities in light-mass system is given to provide some insight into these questions. Level densities over the first 10 MeV or so in excitation energy as deduced from neutron and proton resonances data and from spectra of low-lying bound levels are discussed. To exhibit some of the salient features of these data comparisons to independent-particle (shell) model calculations are presented. Shell structure is predicted to manifest itself through discontinuities in the single-particle level density at the Fermi energy and through variatons in the occupancy of the valence orbitals. These predictions are examined through combinatorial calculations performed with the Grover [Phys. Rev., 157, 832(1967), 185 1303(1969)] odometer method. Before the discussion of the experimenta results, statistical mechanical level densities for spherical nuclei are reviewed. After consideration of deformed nuclei, the conclusions resulting from this work are drawn. 7 figures, 3 tables

  19. Two topics in nuclear physics

    International Nuclear Information System (INIS)

    Thorsson, V.A.

    1992-01-01

    A longstanding problem with the Skyrme Model of the nucleon is that in a classical treatment the potential found in the spin-isospin independent channel is repulsive and thereby in contradiction with observation. In the first part of this thesis, the author analyzes the central part of the nucleon-nucleon potential. The analysis is done following a method proposed by Yamagishi and Zahed involving a double expansion in the soliton separation and the coupling constant. Results are presented of a detailed numerical analysis of the nucleon-nucleon potential in the spin-isospin independent channel in the Skyrme Model. For undistorted pion fluctuations, the numerical results indicate that the pion induced attraction in the central channel is strong enough to cancel the conventional repulsion in the intermediate range to leading order. The case of distorted pion fluctuations is briefly discussed. In the second part of this thesis the possibility is investigated that a phase of matter containing a Bose-Einstein condensate of kaons can exist in the dense interior of neutron stars. The question is specifically addressed of whether such condensation can occur solely through the S-wave interaction of kaons with nucleons. The author derives the equation of state above the condensation threshold in the mean field approximation and investigate particle densities in the condensed state. It is shown that neutron star matter in the presence of a kaon condensate is sufficiently stiff to support a 1.4M circle star, and is therefore compatible with observed neutron star masses. The neutron star contains a core of matter with a kaon condensate and a large fraction of protons. It is suggested that positrons might be produced inside the core and that kaon condensate might serve as a catalyst for fast neutron star cooling via the direct URCA process

    High spin physics is a vast topic addressing the variety of nuclear excitation modes. In the present paper, some general aspects related to recent highlights of nuclear spectroscopy are discussed. The relation between signature splitting and shape changes in the unique parity orbitals is elucidated. The relevance of the Pseudo SU(3) symmetry in the understanding of rotational band structure is addressed. Specific features of rotational bands of intruder configurations are viewed as a probe of the neutron-proton interaction. (author). 36 refs., 5 figs.

    1980-01-01

    Nuclear methods, particularly neutron activation analysis (NAA) provide useful information about elemental constituents in coal and fly ash, but often other techniques are required to supplement NAA data. Spark source mass spectrometry and atomic absorption have been studied as methods for determination of certain elements in coal that are not easily measured by NAA. In work concerned with the chemical speciation of elements in fly ash, a number of analytical techniques have been used; these include NAA, chemical etching and separation, optical and electron microscopy and x-ray diffraction

  6. Nuclear physics in colourful worlds. Quantumchromodynamics and nuclear binding

    International Nuclear Information System (INIS)

    Muether, H.; Engelbrecht, C.A.; Brown, G.E.

    1987-01-01

    When quantumchromodynamics (QCD) is generalized from SU(3) to an SU(N c ) gauge theory, where N c is the number of colours, it depends on only two parameters: N c and the bare quark mass m q . A more general understanding of nuclear physics can be achieved by considering what it would be like in worlds with the number of colours different from 3, and bare quark masses different from the 'empirical' ones. Such an investigation can be carried out within a framework of meson-exchange interactions. The empirical binding energy of nuclear matter results from a very near cancellation between attractive and repulsive terms which are two orders of magnitude larger and may be expected to depend sensitively on the parameters of QCD. It is indeed found that our world is wedged into a small corner of the two-dimensional manifold of m q versus N c . If the number of colours were decreased by one, or the bare quark masses raised by more than 20%, nuclear matter would become unbound. By tracing the origin of this state of affairs, one obtains a clearer picture of the relative importance of various effects on the behaviour of the bulk nuclear matter. In particular, correlations like those embodied in the Coester band of saturation points appear to have a broader degree of validity than is implied by fits to the actual physical world only.

  7. Costing methods for nuclear desalination

    International Nuclear Information System (INIS)

    1966-01-01

    The question of the methods used for costing desalination plants has been recognized as very important in the economic choice of a plant and its optimization. The fifth meeting of the Panel on the Use of Nuclear Energy in Saline Water Conversion, convened by the International Atomic Energy Agency in April 1965, noted this fact and recommended the preparation of a report on suitable methods for costing and evaluating nuclear desalination schemes. The Agency has therefore prepared this document, which was reviewed by an international panel of experts that met in Vienna from 18 to 22 April, 1966. The report contains a review of the underlying principles for costing desalination plants and of the various methods that have been proposed for allocating costs in dual-purpose plants. The effect of the different allocation methods on the water and power costs is shown at the end of the report. No attempt is made to recommend any particular method, but the possible limitations of each are indicated. It is hoped that this report will help those involved in the various phases of desalination projects

  9. Theoretical studies in hadronic and nuclear physics

    International Nuclear Information System (INIS)

    Griffin, J.J.; Cohen, T.D.

    1993-07-01

    Research in the Maryland Nuclear Theory Group focusses on problems in four basic areas of current relevance. The section on Hadrons in Nuclei reports research into the ways in which the properties of nucleons and the mesons which play a role in the nuclear force are modified in the nuclear medium. QCD sum rules supply a new insight into the decrease of the nucleon's mass in the nuclear medium. The quark condensate decreases in nuclear matter, and this is responsible for the decrease of the nucleon's mass. The section on the Structure of Hadrons reports progress in understanding the structure of the nucleon. These results cover widely different approaches -- lattice gauge calculations, QCD sum rules, quark-meson models with confinement and other hedgehog models. Progress in Relativistic Nuclear Physics is reported on electromagnetic interactions in a relativistic bound state formalism, with applications to elastic electron scattering by deuterium, and on application of a two-body quasipotential equation to calculate the spectrum of mesons formed as bound states of a quark and antiquark. A Lorentz-invariant description of the nuclear force suggests a decrease of the nucleon's mass in the nuclear medium similar to that found from QCD sum rules. Calculations of three-body bound states with simple forms of relativistic dynamics are also discussed. The section on Heavy Ion Dynamics and Related Processes describes progress on the (e + e - ) problem and heavy-on dynamics. In particular, the sharp electrons observed in β + irradiation of heavy atoms have recently been subsumed into the ''Composite Particle Scenario,'' generalizing the ''(e + e - -Puzzle'' of the pairs from heavy ion collisions to the ''Sharp Lepton Problem.''

    Insect pests of crops are responsible for immense crop losses in agriculture. Ever since the release of high yielding varieties and improved crop husbandry practices the problems posed by insect pests have been accentuated, as these conditions provide ideal environment for their development. Effective control of insect pests can help greatly in achieving a breakthrough in agricultural production. In order to sustain production and reduce crop losses entomologists all over the world have continued their efforts to devise and develop methods of pest control taking full advantage of the advances made in other branches of science. Consequently, avenues opened by the developments in the field of nuclear energy have also been fully exploited in investigating various pest problems. This communication briefly highlights the various areas of research in which nuclear toots have been fruitfutty used in investigating problems posed by insect pests. (auth.)

    The research activities of the nuclear physics division (SPHN) of DAPNIA (Cea) take place within strong national and international collaborations. Its programs cover a broad range of topics in nuclear physics from low to high energies, they include the structure and dynamics of the nucleus, the structure of the nucleon, the search for phase transitions in nuclear matter, and contribution to the development of nuclear energy. Concerning the structure of the nucleus, SPHN is involved in the study of the structure of light exotic nuclei such as He 6-8 , C 10-11 , Ne 27 and in the study of shape coexistence in Kr isotopes. The experiments are performed at GANIL. SPHN is also involved in the study of the structure of Md 251 through experiments made in Finland. Near-barrier and sub-barrier fusion of light unstable nuclei and their respective stable isotopes with U 238 targets are studied in Louvain-la-Neuve (Belgium). Concerning nuclear phase transitions, the purpose of our activities is twofold: the study of the liquid-gas phase transition in nuclei at relatively low incident energies and the search for the quark-gluon plasma (QGP) at very high energies. We look for QGP signatures in 2 experiments: Phenix with the accelerator RHIC at Bnl and Alice at the LHC (CERN). Concerning the structure of the nucleon, SPHN is involved in 2 experimental programs both using electromagnetic probes, one to obtain information on the spin carried by the gluons in the proton (Compass at CERN) and the other to extract information on generalized parton distributions by means of deeply virtual Compton scattering (Clas at Jlab). Concerning nuclear energy, the activities are focused along 3 main lines: spallation studies, neutron cross-section measurements and application oriented modeling. (A.C.)

  6. Some nuclear physics aspects of BBN

    Science.gov (United States)

    Coc, Alain

    2017-09-01

    Primordial or big bang nucleosynthesis (BBN) is now a parameter free theory whose predictions are in good overall agreement with observations. However, the 7 Li calculated abundance is significantly higher than the one deduced from spectroscopic observations. Nuclear physics solutions to this lithium problem have been investigated by experimental means. Other solutions which were considered involve exotic sources of extra neutrons which inevitably leads to an increase of the deuterium abundance, but this seems now excluded by recent deuterium observations.

    2005-01-01

    Nuclear physics and energy research depends on and advances science and technology outside of the nuclear field. Perhaps the most commonly perceived benefits to society from nuclear and particle physics are those derived from particle beam technology. Charged particle accelerators play an increasing role in applications in industry and medicine. Neutrons produced with a high power proton accelerator in a spallation process are used from basic research, radiography in automotive industry (example fuel cell development) to transmutation of highly radioactive fission products. Production and acceleration of ultra cold neutrons provide intense and almost mono-energetic neutrons to study soft matter. Heavier radioisotopes are used in a wide field ranging from medicine to semiconductor industry (ion implantation for doping or coating technologies). Concrete examples and future trends will be given. Detailed understanding of ion physics at low energy allows the design of compact accelerator mass spectroscopy (close to table top size). The ability to measure concentrations of specific radioactive isotopes even below the natural radioactivity widens the scope of applications from archaeology, climate research to food industry. Such a compact device is close to commercialisation. (author)

    2014-03-01

    The challenges of Nuclear Physics, especially in understanding strongly interacting matter in all its forms in the history of the universe, place ever higher demands on the tools of the field, including the workhorse, accelerators. These demands are not just higher energy and higher luminosity. To recreate the matter that fleetingly was formed in the origin of the heavy elements, we need higher power heavy-ion accelerators and creative techniques to harvest the isotopes. We also need high-current low-energy accelerators deep underground to detect the very slow rate reactions in stellar burning. To explore the three dimensional distributions of high-momentum quarks in hadrons and to search for gluonic excitations we need high-current CW electron accelerators. Understanding the gluonic structure of nuclei and the three dimensional distributions of partons at lower x, we need high-luminosity electron-ion colliders that also have the capabilities to prepare, preserve and manipulate the polarization of both beams. A search for the critical point in the QCD phase diagram demands high luminosity beams over a broad range of species and energy. With advances in cavity design and construction, beam manipulation and cooling, and ion sources and targets, the Nuclear Physics community, in the U.S. and internationally has a coordinated vision to deliver this exciting science. This work is supported by DOE, Office of Nuclear Physics, under contract DE-AC02-06CH11357.

It summarizes the outcome of the nuclear astrophysics town meeting that was held on August 21 - 23, 2014 in College Station at the campus of Texas A&M University in preparation of the NSAC Nuclear Science Long Range Plan. It also reflects the outcome of an earlier town meeting of the nuclear astrophysics community organized by the Joint Institute for Nuclear Astrophysics (JINA) on October 9 - 10, 2012 Detroit, Michigan, with the purpose of developing a vision for nuclear astrophysics in light of the recent NRC decadal surveys in nuclear physics (NP2010) and astronomy (ASTRO2010). The white paper is furthermore informed by the town meeting of the Association of Research at University Nuclear Accelerators (ARUNA) that took place at the University of Notre Dame on June 12 - 13, 2014. In summary we find that nuclear astrophysics is a modern and vibrant field addressing fundamental science questions at the intersection of nuclear physics and astrophysics. These questions relate to the origin of the elements, the nuclear engines that drive life and death of stars, and the properties of dense matter. A broad range of nuclear accelerator facilities, astronomical observatories, theory efforts, and computational capabilities are needed. With the developments outlined in this white paper, answers to long-standing key questions are well within reach in the coming decade.

    In comparison with other aspects of physical science, nuclear and radiochemistry are small contributors to the overall scheme of things. Nuclear science is, however, an important player in various aspects of medicine, life sciences, industrial technology, physical sciences, archeometry and art, and theoretical/computational sciences. This new book fills the need for a contemporary text with a good mix of simple introductory theory, experimental methodology, and instrumentation for beginning students of nuclear science

    Full text: Research in the Department of Nuclear Physical Chemistry concentrates on three main topics: 1. Radiochemistry of transactinide elements; 2. Environmental radioactivity and related problems; 3. Preparation and applications of radioactive isotopes. The investigations on radiochemistry of transactinide elements are carried out in the Laboratory of Chemistry and Radiochemistry. Practical difficulties due to short half-lives and very low cross sections of formation of the superheavy nuclei are being overcome by developing fast and efficient methods of chemical separation, basing mostly on ion-exchange processes which are thoroughly studied via model experiments on lighter homologues of the elements of interest. During the year 2001, work with composite ferrocyanide sorbents was continued, and the efforts resulted in a patent application. The developed ion-exchangers (whose characteristics are constantly checked and improved in the laboratory) can find practical applications in environmental protection as well as in fundamental studies on the most exotic elements: 104 Rf, 105 Db, 106 Sg, 107 Bh, 108 Hs, and more. As to the latter, the discovery in Dubna of the relatively long-lived element 114 (t 1/2 =30s) gives hope that studies on aqueous chemistry of the elements Z =107 would be feasible. In this context, chemical methods of separation and identification of the heaviest elements are necessary to know the behaviour of the whole decay chains, for example: 114 -α-112 -α-110 -α-108 -α-106. The group is contributing its expertise to the top specialist international co-operation, involving the Joint Institute of Nuclear Research, Dubna, Russia, the Institute of Geochemistry and Analytical Chemistry of the Russian Academy of Sciences, Moscow, Russia, and three German institutions: the Technical University of Dresden, the University of Mainz, and the GSI Darmstadt. The Environmental Radioactivity Laboratory is following up traces of α, β, and γ radioactive

    In this review, we discuss the current status of research in nuclear physics which is being carried out in different centers in the world. For this purpose, we supply a short account of the development in the area which evolved over the last nine decades, since the discovery of the neutron. The evolution of the physics of the atomic nucleus went through many stages as more data became available. We briefly discuss models introduced to discern the physics behind the experimental discoveries, such as the shell model, the collective model, the statistical model, the interacting boson model, etc., some of these models may be seemingly in conflict with each other, but this was shown to be only apparent. The richness of the ideas and abundance of theoretical models attests to the important fact that the nucleus is a really singular system in the sense that it evolves from two-body bound states such as the deuteron, to few-body bound states, such as 4 He, 7 Li, 9 Be, etc. and up the ladder to heavier bound nuclei containing up to more than 200 nucleons. Clearly, statistical mechanics, usually employed in systems with very large number of particles, would seemingly not work for such finite systems as the nuclei, neither do other theories which are applicable to condensed matter. The richness of nuclear physics stems from these restrictions. New theories and models are presently being developed. Theories of the structure and reactions of neutron-rich and proton-rich nuclei, called exotic nuclei, halo nuclei, or Borromean nuclei, deal with the wealth of experimental data that became available in the last 35 years. Furthermore, nuclear astrophysics and stellar and Big Bang nucleosynthesis have become a more mature subject. Due to limited space, this review only covers a few selected topics, mainly those with which the authors have worked on. Our aimed potential readers of this review are nuclear physicists and physicists in other areas, as well as graduate students interested

    The volume includes the presentations given on the International Meeting 'Selected Topics on Nuclear Methods for Non-nuclear Applications'. The meeting was organized by the Project CECOA. The Project 'CEnter for COoerative Activities' (CECOA) of the Institute for Nuclear Research and Nuclear Energy (INRNE) of Bulgarian Academy of Sciences is part of the Program 'Creating of Infrastructure' of Bulgarian Ministry of Science and Education. The CECOA-project unifies the groups of INRNE doing research in the field of nuclear methods. Four Laboratories of INRNE are members of CECOA-project: Moessbauer Spectroscopy and Low Radioactivity Measurements, High-Resolution Gamma-Spectroscopy, Neutron Methods in Condensed Matter, Neutron Optics and Structure Analysis. Taking into account the leading role of education on nuclear physics the Project includes program devoted to the training on nuclear physics. The presented volume contains 23 contributed papers. The contributions are separated in 6 sections. The section 'Nano technology' includes 5 papers. The activity in this field within the Project reveals the collaboration with other Institutes of Bulgarian Academy of Sciences as well as large international contacts. The section 'Radioecology and Radioactive Waste' is two fold. Part of the contributions of the section manifests the connection of the CECOA with small enterprises. The contacts are on the level of common projects concerning the investigations, remediation and release of radioactively contaminated terrain, soils, water, buildings and materials around the former uranium processing industry. Another part of the section is devoted to the application of nuclear methods to the treatment of radioactive waste produced by nuclear power stations. The section 'Neutron Physics' reveals the activity within the Project connected with the study of new materials using polarized neutrons and neutron diffraction methods. The section 'Nuclear Physics' is an introduction to some

    Moniz, E.J.

    1988-01-01

    Nuclear physics is the study of strongly interacting matter and of the forces which govern its structure and dynamics. The goal of this paper is to give an understanding of nuclei as quantal many-body systems and of the nature of the strong force, ultimately in terms of the presumed underlying theory of quantum chromodynamics. The latter task will require a deeper understanding of hadron structure and of color confinement and, in turn, will provide the basis for exploring the structure of matter under extreme conditions, such as very high density or temperature. This program covers a very broad range of phenomena, theoretical concepts, and experimental tools and is reflected in the diverse degrees of freedom invoked in various contexts. This is indicated where degrees of freedom loosely identified with successively smaller distance scales are indicated. Very importantly, theoretical bridges have been built between the phenomenological descriptions associated with each set of degress of freedom. The mean field, determined self-consistently from the interactions of nucleons in quantum orbits, provides the basis for much of the authors microscopic understanding of nuclear structure and of our characterization of nuclear scattering processes. However, the authors are only beginning to address quantitatively the physics associated with short-range correlations, physics which takes us beyond the mean field description. The nuclear force has a very successful semi-phenomenological description in terms of hadronic degrees of freedom, both mesons and nucleon isobars. More problematic, of course, is our understanding of hadron structure and dynamics in terms of QCD

  20. Traditional nuclear physics as a test of nuclear exotics

    International Nuclear Information System (INIS)

    Sapershtein, E.E.; Starodubskii, V.E.

    1989-01-01

    The review considers the testing of some exotic hypotheses about the properties of the nucleon in a nuclear medium in phenomena of traditional nuclear physics. The hypothesis of nucleon swelling proposed to explain the EMC effects is considered in detail. The consequences of this hypothesis for the charge densities and cross sections for scattering of fast electrons and protons by nuclei are analyzed. Also considered are the Nolen--Schiffer anomaly, the Coulomb sum rule for inelastic electron scattering, y scaling, and some other nuclear processes. It is shown that one can estimate the possible scale of nuclear exotics by analyzing many of these phenomena. Thus, examination of high-precision data on the elastic scattering of electrons with energy 500--700 MeV using density distributions calculated on the basis of the self-consistent theory of finite Fermi systems yields a restriction on the amount of nucleon swelling: α=δr N /r N approx-lt 10%. A similar analysis for protons with energy 0.8--1.0 GeV using Glauber theory gives α approx-lt 6%. An even more stringent restriction, α approx-lt 3%, follows from data on y scaling in 56 Fe

    1995-01-01

    Semiconductor detectors for elementary particle physics and nuclear physics in the energy range above 1 GeV are briefly reviewed. In these two fields semiconductor detectors are used mainly for the precise position sensing. In a typical experiment, the position of a fast charged particle crossing a relatively thin semiconductor detector is measured. The position resolution achievable by semiconductor detectors is compared with the resolution achievable by gas filled position sensing detectors. Semiconductor detectors are divided into two groups; (i) classical semiconductor diode detectors and (ii) semiconductor memory detectors. Principles of the signal formation and the signal read-out for both groups of detectors are described. New developments of silicon detectors of both groups are reported. copyright 1995 American Institute of Physics

    Applications of QCD sum-rule methods to the physics of nuclei are reviewed, with an emphasis on calculations of baryon self-energies in infinite nuclear matter. The sum-rule approach relates spectral properties of hadrons propagating in the finite-density medium, such as optical potentials for quasinucleons, to matrix elements of QCD composite operators (condensates). The vacuum formalism for QCD sum rules is generalized to finite density, and the strategy and implementation of the approach is discussed. Predictions for baryon self-energies are compared to those suggested by relativistic nuclear physics phenomenology. Sum rules for vector mesons in dense nuclear matter are also considered.

    Purpose: In order to judge the fuel failures, if any, without opening a reactor container for BWR type reactors, a method has been described for measuring the difference between the temperature dependent iodine spike value and the pressure dependent iodine spike value in the pressure vessel. Method: After the scram of a nuclear reactor, steam generated by decay heat is condensed in a remaining heat exchanger and cooling water is returned through a recycling pipe line to a reactor core. At the same time, a control rod drive system pump is operated, the reactor core is filled with the cooling water. Then, the coolant is taken from the recycling pipe line to cool the reactor core. After applying the temperature fluctuation, the cooling water is sampled at a predetermined time interval at a sampling point to determine the changes with time in the radioactive concentration of iodine. When the radioactivity of iodine in the cooling water is lowered sufficiently by a reactor purifying system, the nuclear reactor vessel is depressurized. After applying pressure fluctuation, iodine spike value is determined. (Kawakami, Y.)

    This Japan Hadron Project workshop was held on May 19 and 20, 1995, at Institute for Nuclear Study, University of Tokyo. The Neutron Arena planned in JHP is the facility that uses the spallation neutrons generated by high energy protons, and its utilization is planned in wide research fields. On the other hand, in the neutron scattering facility in the booster utilization facility of National Laboratory for High Energy Physics, the researches of verifying parity nonconservation and time reversal break have been carried out so far. It is necessary to accurately measure the reaction cross section of neutrons in low energy region. This workshop was planned for examining the Neutron Arena by the researchers related to elementary particles and atomic nuclei. In the workshop, lectures were given on the break of the reversal symmetry of time and space in neutron-atomic nucleus reaction, neutrino physics, neutron capture and celestial nuclear physics, neutron-induced nucleosynthesis, development and utilization of very cold neutron interferometer using multi-layer film mirror, research on gravity using neutron interferometer, electric polarizability of neutrons, β decay of neutrons, possibility of research on basic symmetry problem at E-arena, β decay in storage ring, neutron electric dipole moment using ultracold neutrons, magnetic confinement and control of ultracold neutrons, and outline of JHP neutron source.

    Purpose: To easily attain the power decreasing in a HWLWR type reactor and improve the reactor safety. Method: The method is applied to a nuclear reactor in which the reactor reactivity is controlled by control rods and liquid posions dissolved in moderators. Means for forecasting the control rod operation amount required for the reactor power down and means for removing liquid poisons in the moderators are provided. The control rod operation amount required for the power down is forecast before the power down and the liquid poisons in the moderators are removed. Then, the control rods are inserted into a deep insertion position to reduce the reactor power. This invention can facilitate easy power down, as well as provide effects of improving the controllability in the usual operation and of avoiding abrupt power down which leads to an improved availability.

The following lectures of nuclear interest were given: The N-body problem (relativistic and non-relativistic approaches); The shell model (towards a unified of the nuclear structure); Pairing correlations in extreme conditions; Collective excitations in nuclei; Exotic nuclei (production, properties and specificities); Exotic nuclei (halos); Super and hyper deformation (from discrete to continuum, from EUROGAM to EUROBALL); and The spectroscopy of fission fragments. Important new facts are reported and discussed theoretically, concerning the nuclei in high excitation and high states and of the nuclei far off stability. Important technical achievements are reported among which the production of radioactive beams, sophisticated multi-detectors as well as significant advances in the nuclear theoretical methods. The double goal of training of young researchers and of permanent formation and information of the older ones seems to have been reached

    Symmetries session is always one of the conference highlights. There, progress on Standard Model tests employing atomic nuclei or nuclear physics methods - which are used to probe complimentary sectors to large particle physics experiments, for example atomic and neutron EDM experiments - is reported. Recent progress was reported in the sector of nuclear beta decay as related to the testing of the CKM unitarity matrix, as well as the W-mass and the Weak Mixing Angle. The muon anomalous magnetic moment and its sensitivity for probing new physics and future experimental improvements are anticipated and showcase the activity in the field. The large oral and poster presentation program was extended to include special presentations by the IUPAP young scientist award winners. This prize is given out in the field of nuclear physics every three years during the INPC conference, and this year's winners were: Kenji Fukushima (Yukawa Institute for Theoretical Physics, Kyoto University), Peter Mueller (Argonne National Laboratory), and Lijuan Ruan (Brookhaven National Laboratory). These three scientists represent future excellence in nuclear physics in the fields of theoretical QCD, experimental techniques related to quark gluon plasma, and precision experiments in low energy nuclear halo physics. One keenly anticipated presentation, 'The Lamb shift in muonic hydrogen experiment', presented the results of the measurement of the proton rms charge radius. These results claimed a 5 sigma deviation from the established CODATA-value and in the future more tests will be needed to verify these findings. INPC 2010 made a special effort to attract many graduate students and post-doctoral fellows to the conference. This was achieved by a number of efforts, for example, TRIUMF combined its traditional summer school with the US National Science Foundation summer school for nuclear physics, and offered the school directly prior to the conference. This allowed the school to recruit some of the INPC

    Broyden's method, widely used in quantum chemistry electronic-structure calculations for the numerical solution of nonlinear equations in many variables, is applied in the context of the nuclear many-body problem. Examples include the unitary gas problem, the nuclear density functional theory with Skyrme functionals, and the nuclear coupled-cluster theory. The stability of the method, its ease of use, and its rapid convergence rates make Broyden's method a tool of choice for large-scale nuclear structure calculations

  11. New methods in nuclear reaction theory

    1979-01-01

    Standard nuclear reaction methods are limited to treating problems that generalize two-body scattering. These are problems with only one continuous (vector) degree of freedom (CDOF). The difficulty in extending these methods to cases with two or more CDOFs is not just the additional numerical complexity: the mathematical problem is usually not well-posed. It is hard to guarantee that the proper boundary conditions (BCs) are satisfied. Since this is not generally known, the discussion is begun by considering the physics of this problem in the context of coupled-channel calculations. In practice, the difficulties are usually swept under the rug by the use of a highly developed phenomenology (or worse, by the failure to test a calculation for convergence). This approach limits the kind of reactions that can be handled to ones occurring on the surface of where a second CDOF can be treated perturbatively. In the past twenty years, the work of Faddeev, the quantum three-body problem has been solved. Many techniques (and codes) are now available for solving problems with two CDOFs. A method for using these techniques in the nuclear N-body problem is presented. A set of well-posed (connected kernal) equations for physical scattering operators is taken. Then it is shown how approximation schemes can be developed for a wide range of reaction mechanisms. The resulting general framework for a reaction theory can be applied to a number of nuclear problems. One result is a rigorous treatment of multistep transfer reactions with the possibility of systematically generating corrections. The application of the method to resonance reactions and knock-out is discussed. 12 figures

    Primary emphasis is placed on understanding the nature of nucleon-nucleon and meson-nucleon interactions and on determining the consequences of such microscopic interactions in nuclear systems. We have constructed models of baryons which smoothly interpolate between currently popular bag and Skyrme models of hadrons and provide a vehicle for introducing the notions of quantum chromodynamics to low energy nuclear physics without violating the constraints of chiral invariance. Such models have been used to study the nucleon-nucleon interaction, the spectrum of baryons, and the important question of the radius of the quark bag. We have used many-body techniques to consider a variety of problems in finite nuclei and infinite many-body systems. New light has been shed on the nuclear coexistence of spherical and deformed states in the A = 18 region as well as the role of genuine three-body forces in this region. Phenomenological studies of infinite systems have led to a number of predictions particularly regarding the spin-polarized quantum liquids of current experimental interest. Microscopic many-body theories, based on the parquet diagrams, have been improved to a fully quantitative level for the ground state properties of infinite many-body systems. Finite temperature theories of nuclear matter, important in the study of heavy ion reactions, have been constructed. An expanded program in heavy ion theory has led to major advances in the multi-dimensional barrier penetration problem. Activities in nuclear astrophysics have provided a far more reliable description of the role of electron capture processes in stellar collapse. As a consequence, we have been able to perform legitimate calculations of the unshocked mass in Type II supernovae

    The 1983 Joliot-Curie school was aimed at reviewing some outstanding aspects of current research in nuclear spectroscopy. The recent developments of high and very high spin states study are presented. The most important experimental methods and explaining concepts concerning the ground states and the first excited levels of nuclei far from beta stability are reviewed. Spin-isospin excitations are dealt with from a theoretical point of view and also for the most outstanding experimental results. At last, basic concepts and limits of the shell model nuclear description are outlined and illustrated [fr

  17. Resonances: from nuclear physics to mesoscopic systems

    International Nuclear Information System (INIS)

    Ferreira, Lidia S.; Maglione, Enrico

    2007-01-01

    Resonances are one of the most interesting phenomena in many fields of physics which lead to important findings. In the quantum world, systems with electrons, hadrons or atoms provide enormous amount of data on resonances, leading to the discovery of new states of matter. In nuclear physics, the recent findings on exotic nuclei, added to the list many new examples, which are important not only as direct data on resonances, but also for the production of new isotopes in regions of the nuclear chart which were 'terra incognita', until recently. With recent developments in microelectronics it is possible to create in the laboratory almost two dimensional wave guides where the motion of the electrons can exhibit typical quantum effects. The geometry of systems, such as bends, corners or crosses, has a strong influence on the conduction properties of the electrons, since it can create the appropriate conditions required for the formation of bound states or resonances in the conduction channels. Therefore it is quite important to have an accurate description of the relation between geometry and observables, which in a theoretical perspective emerges naturally from the solution of a multichannel eigenvalue problem. The study of resonances and their behaviour in these domains of physics, will be the purpose of the lecture. (Author)

    1988-01-01

    The spectator model, a general approach to the relativistic treatment of nuclear physics problems in which spectators to nuclear interactions are put on their mass-shell, will be defined nd described. The approach grows out of the relativistic treatment of two and three body systems in which one particle is off-shell, and recent numerical results for the NN interaction will be presented. Two meson-exchange models, one with only 4 mesons (π, σ, /rho/, ω) but with a 25% admixture of γ 5 coupling for the pion, and a second with 6 mesons (π, σ, /rho/, ω, δ, and /eta/) but a pure γ 5 γ/sup mu/ pion coupling, are shown to give very good quantitative fits to NN scattering phase shifts below 400 MeV, and also a good description of the /rho/ 40 Cα elastic scattering observables. 19 refs., 6 figs., 1 tab

    Full text: In the Laboratory of Chemistry and Radiochemistry, research on chemical properties of super heavy elements Rf, Db and Sg, in model systems with their homologs Zr, Hf, Nb, Ta, Mo and W in aqueous solutions, was continued. The main subject of study was sorption of these elements on ion exchange resins, on ferrocyanide sorbents and on liquid anion exchanger Aliquat 336. Simultaneously, experiments on ion exchange behaviour of Tc and Re as homologs of Bh (Z =107) and of Os as that of Hs (Z =108) in the online and offline systems were carried out. Experiments with Hg and Pb as analogs of elements Z=112 and Z=114, started only in 1999, resulted in elaboration of a very fast continuous method for isolation of short-lived (t 1/2 ≥ 3 s) mercury isotopes. The above studies were performed in cooperation with the Joint Institute of Nuclear Research, Dubna, Russia, the Institute of Geochemistry and Analytical Chemistry of the Russian Academy of Sciences, Moscow, Russia, the Technical University of Dresden, Germany, the University of Mainz, Germany and the GSI Darmstadt, Germany. The Laboratory of Environmental Radioactivity was continuing two main directions of their activities: weekly reports on continuous monitoring of the ground level air and research on the environmental radioactivity. The results of six years of systematic measurements of long-lived γ-emitters present in the ground level air were the subject of a PhD thesis defended in May 1999. The main project in the Laboratory in 1999 was that on accumulation of Pu, Am, Cm, Sr and Eu isotopes in bones of wild herbivorous animals. Its major part, devoted to the α-emitters, has been completed. Another important research (performed in collaboration with the Nuclear Spectroscopy Department of the Institute) concerned development of a method for determination of high-energy pure β - emitters via measurement of Bremsstrahlung photons produced on a metal absorber of optimised thickness. The Laboratory was also

    2002-04-01

    Nuclear fission is presently a contested method of electricity production. The issue of nuclear waste management stands out among the reasons why. On the other hand, the nuclear industry has demonstrated its capacity to reliably generate cheap electricity while producing negligible amounts of greenhouse gases. These assets explain why this form of energy is still considered among the options for the long term production of electricity at least in developed countries. However, in order to tackle the still not adequately answered question of the waste, new schemes may have to be considered. Among those which have been advanced recently, the less polluting cycles such as those based on Thorium rather than Uranium and/or the transmutation of the minor actinides and some long lived fission products of the present cycle have been actively investigated. In both cases, it turns that the basic knowledge underlying these methods is either missing or incomplete. This situation opens a window of opportunity for useful contributions from basic nuclear physicists. This article describes some of them and presents the ongoing activities as well as some of the projects put forth for the short or medium term. .

    Nuclear safeguards systems are concerned, in part, with the physical protection of nuclear materials. The function of a physical protection system is to define the facility against adversary activities which could lead to theft of nuclear material or sabotage resulting in a radiological release. The Safeguards Network Analysis Procedure (SNAP) provides a convenient and standard analysis methodology for the evaluation of physical protection system analysis. This paper describes a detailed application of SNAP to a hypothetical nuclear facility

    A method of deriving three dimensional image information from an object using nuclear magnetic resonance signals comprises subjecting the object to a continuous, static magnetic field and carrying out the following set of sequential steps: 1) exciting nuclear spins in a selected volume (90deg pulse); 2) applying non-aligned first, second and third gradients of the magnetic field; 3) causing the spins to rephase periodically by reversal of the first gradient to produce spin echoes, and applying pulses of the second gradient prior to every read-out of an echo signal from the object, to differently encode the spin in the second gradient direction for each read-out signal. The above steps 1-3 are then successively repeated with different values of gradient of the third gradient, there being a recovery interval between the repetition of successive sets of steps. Alternate echoes only are read out, the other echoes being time-reversed and ignored for convenience. The resulting signals are appropriately sampled, set out in an array and subjected to three dimensional Fourier transformation. (author)

    In order to carry out the sort of probabilistic analysis referred to by Farmer (Contemp. Phys.; 22:349(1981)), it is necessary to have a good understanding of the processes involved in both normal and accident conditions in a nuclear reactor. Some of these processes, for a variety of different reactor systems, are considered in sections dealing with the neutron chain reaction, the removal of heat from the reactor, material problems, reliability of protective systems and a number of specific topics of particular interest from the point of view of physics or engineering.

  11. Super-radiance in Nuclear Physics

    International Nuclear Information System (INIS)

    Auerbach, N

    2015-01-01

    The theory of the super-radiant mechanism as applied to various phenomena in nuclear physics is presented. The connection between super-radiance and the notion of doorway is presented. The statistics of resonance widths in a many-body Fermi system with open channels is discussed. Depending on the strength of the coupling to the continuum such systems show deviations from the standard Porter-Thomas distribution. The deviations result from the process of increasing interaction of the intrinsic states via the common decay channels. In the limit of very strong coupling this leads to super-radiance. (paper)

    Jagannathan, V.

    1993-01-01

    Reactor physics design methods are aimed at safe and efficient management of nuclear materials in a reactor core. The design methodologies require a high level of integration of different calculational modules of many a key areas like neutronics, thermal hydraulics, radiation transport etc in order to follow different 3-D phenomena under normal and transient operating conditions. The evolution of computer hardware technology is far more rapid than the software development and has rendered such integration a meaningful and realizable proposition. The aim of this paper is to assess the state of art of the physics design codes used in Indian thermal power reactor applications with respect to meeting the design, operational and safety requirements.

    The XXXVII Brazilian Meeting on Nuclear Physics (or XXXVII RTFNB 2014) gave continuity to a long sequence of workshops held in Brazil, devoted to the study of the different aspects of nuclear physics. The meeting took place in the Maresias Beach Hotel, in the town of Maresias (state of São Paulo) from 8th to 12th September 2014. Offering gentle weather, a charming piece of green land of splendid natural beauty with beach and all amenities, the place had all the conditions for very pleasant and fruitful discussions. The meeting involved 162 participants and attracted undergraduate and graduate students, Brazilian and South American physicists and invited speakers from overseas (USA, Italy, Spain, France, England, Switzerland, Germany and South Corea). In the program we had plenary morning sessions with review talks on recent developments in theory, computational techniques, experimentation and applications of the many aspects of nuclear physics. In the parallel sessions we had a total of 58 seminars. This volume contains 60 written contributions based on these talks and on the poster sessions. Evening talks and poster sessions gave still more insight and enlarged the scope of the scientific program. The contributed papers, representing mainly the scientific activity of young physicists, were exhibited as posters and are included in the present volume. Additional information about the meeting can be found at our website: http://www.sbfisica.org.br/~rtfnb/xxxvii-en Support and sponsorship came from brazilian national agencies: Conselho Nacional de Desenvolvimento Científico e Tecnoógico (CNPq); Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Fundação de Amparo á Pesquisa do Estado de São Paulo (FAPESP); Fundação de Amparo á Pesquisa do Estado do Rio de Janeiro (FAPERJ); Sociedade Brasileira de Física (SBF) and Instituto de Física da Universidade de São Paulo (IFUSP).

    1984-01-01

    The advances of space technology ushered in a new era in the development of man's ideas about the solar system. The flights of space vehicles to moon, Venus, Mars and other planets made it possible to obtain quite new information on the composition, structure and properties of matter in the solar system. In these studies a prominent role is played by remote and contact nuclear physics methods of analyzing extraterrestrial matter - gamma spectrometry, X-ray spectrometry, alpha spectrometry and neutron spectrometry. At present practically any space vehicle bound for planets carries scientific instrumentation based on nuclear physics methods of analysis. The use of gamma and X-ray spectroscopy for obtaining information about composition, structure and properties of the matter of the moon and planets is reviewed. (author)
