Electron Photodetachment from Ions and Elastic Collision Cross Sections for O, C, Cl, and F

Abstract

Photodetachment cross sections for ${\mathrm{O}}^{-}$, ${\mathrm{C}}^{-}$, ${\mathrm{Cl}}^{-}$, and ${\mathrm{F}}^{-}$ have been computed in the energy range from threshold to 50 ev by the Klein-Brueckner method. Elastic cross sections for electron scattering from O, C, Cl, and F in the energy range 0-15 ev have also been computed. The method of calculation is described and the results compared with earlier theoretical and experimental work.
