Relativistic Dirac Calculations for Electrons Scattering from Mg and Ca Atoms at Different Energies

Abstract

The cross sections of the electron scattering from atoms and spin polarization has been calculated for the scattering of electrons from Mg and Ca atoms at different energies using the relativistic Dirac equation. The interest of these calculations is to obtain an information about the scattering process. The incident electron- target interaction is represented by an a potential, which is consist of a sum of real model potentials used in the solution of relativistic Dirac equation. The comparison of the results obtained by this method are very good agreement with the other available results.
