Study of neutron rich neon isotopes

Tengblad, Olof; García Borge, María José; Johannsen, L.; Jonson, B.; Lindroos, M.; Nilsson, T.; Nyman, G.

5 pages, 4 figures, 2 tables.-- PACS nrs.: 27.30.+t; 21.90.+f; 23.90.+w. | The half-lives and P(n)-values of the neutron rich isotopes Ne-26-29 have been determined. The results are compared to shell-model calculations and good agreement is found except for Ne-29, where the half-life exceeds the pre...

Structure of neutron-rich oxygen isotopes

Cortina-Gil, D.; Fernández-Vázquez, J.; Aumann, T.; Baumann, T.; Benlliure, J.; García Borge, María José

4 pages, 1 table, 2 figures. | One-nucleon removal reactions at relativistic energies have been used as a spectroscopic tool for obtaining information about the ground state of neutron-rich oxygen isotopes. Using the FRS at GSI, the longitudinal momentum distributions of the emerging fragments after...

Shape transitions in neutron-rich Yb, Hf, W, Os, and Pt isotopes within a Skyrme Hartree-Fock + BCS approach

Sarriguren, Pedro; Rodríguez-Guzmán, R.; Robledo, L. M.

9 pages, 1 table, 7 figures.-- PACS nrs.: 21.60.Jz; 27.70.+q; 27.80.+w. | Self-consistent axially symmetric Skyrme Hartree-Fock plus BCS calculations are performed to study the evolution of shapes with the number of nucleons in various chains of Yb, Hf,W, Os, and Pt isotopes from neutron number N =...

New information on β-delayed neutron emission from Be-12, Be-14

Bergmann, U. C.; Axelsson, L.; García Borge, María José; Fedoseyev, V. N.; Forssén, C.; Fynbo, H. O. U.

17 pages, 3 tables, 5 figures, 1 appendix.-- PACS nrs.: 23.40.Hc; 27.20.+n. | The β-delayed neutron branches from neutron-rich Be-isotopes have been measured with a setup sensitive down to thermal energies. For Be-14 a new value of P(n) = 101 ± 4% has been found for the total neutron-emission probab...

Halo signals in the beta decay of O-28

Poves, A.; Retamosa, J.; García Borge, María José; Tengblad, Olof

3 pages, 2 figures.-- PACS nrs.: 21.10.Dr; 21.10.Gv; 21.60.Cs; 23.40.–s. | We present a study of the 'hypothetical', doubly magic and extremely neutron-rich nucleus O-28. In our description O-28 is a bound nucleus and exhibits some of the features of a neutron halo, where a particular channel for be...
