Numerical comparison between relativistic and nonrelativistic theory for scattering of slow electrons from atoms
By means of the results for phase shifts, differential cross-sections, and spin polarization in scattering of slow electrons from screened Hg, Xe and Ar nuclei the Mott-theory is compared with its nonrelativistic approximation. For electron energies below 200 eV we find an increasing agreement of the results of the two theories with decreasing atomic number of the scatterer; for Ar both theories yield the same result.
