a Study of Relativistic Effects in the Inner Shell Ionization of Atoms by Electrons.
Abstract
Total cross sections for the ionization of the inner atomic shells by electrons were calculated in the relativistic plane wave born approximation (RMPWBA) using the Moller interaction between the incident and ejected electrons. Dirac plane and hydrogenic wave functions are used to describe the projectile and atomic electrons, respectively. The importance of using the Moller interaction which incorporates the retardation effect is investigated by comparing the results of the RMPWBA with those obtained from the use of the Coulomb interaction between two electrons. For incident energies of a few times the ionization energy, these two results differ almost by a factor two. The use of the Coulomb interaction alone fails to provide reasonable agreements between the calculations and the observations at these energies in the plane wave born approximation.
