Total cross sections for elastic scattering of positrons for silicon, gallium and antimony atoms
MetadataShow full item record
In this paper, elastic total cross sections of positrons which is scattered by bound silicon, gallium and antimony atoms have been calculated. The calculation of elastic scattering cross section for E<10 keV made with thepartial wave expansions. The total elastic cross section have been taken for positrons of silicon, gallium and antimony calculated by Öztürk, Williamson and Antolak in the energy region 10 eV - 10 keV. In this article the screened Rutherford cross section with the spin-relativistic factor have been used for elastic scattering in the energy region 10 keV - 4 MeV.
