Espectroscopia optogalvânica: alguns aspectos relevantes/ Optogalvanic spectroscopy: some relevants aspects

Pereira, Robson Valentim; Pessine, Francisco B. T.

Resumo em inglês In this work we present the optogalvanic effect in ionized gases in an historical perspective. This effect was observed for the first time by Foote and Mohler in 1925, and explained by Penning in 1928 for mixtures (Ne-Ar) and pure gases (or vapours) in 1937. Also, we show some aspects of the contributions of Romenian authors for the development of optogalvanic spectroscopy, which was used as a new technique only after 1964.
