Theoretical Calculations for Elastic Scattering of Electrons from Xe Atom

The differential cross sections and spin polarization parameters for the spin-electrons elastically scattered from spinless Xe atoms are calculated by relativistic partial expansion method. In the processes the incident electrons are treated as moving relativistically in an effective central potential V(r) which is calculated by relativistic self-consistent-field method with Slater local exchange approximations. The validity of the theoretical method can be accessed by detailed comparison with recent complete experimental data.
