Elastic Positron Scattering from Zinc and Cadmium in the Relativistic Polarized Orbital Approximation
Languages of publication
Results of relativistic calculations on the elastic positron scattering from zinc and cadmium atoms are presented in the low-energy region. The ab initio calculated polarization potentials applied in these calculations were obtained by solving the coupled Dirac-Hartree-Fock equations. It is shown that the indirect relativistic effects play an important role in the description of the scattering process. Particularly, relativity has a great influence on values of scattering lengths.
