Determination of partial single differential electron ionization cross sections of H2

Abstract

The partial single differential cross sections (PSDCS) for the ions H2+ and H+ resulting from the direct and dissociative ionization of H2 by electron impact have been calculated employing a semi-empirical approach. The calculations are made as a function of the secondary/ejected electron energy at 500 and 1000 eV incident electron energies. The partial ionization cross sections (PICS) for direct and dissociative ionization have also been calculated with incident electron energies varying from the ionization threshold to 10 keV. The results are compared with the available experimental data.
