Abstract
We present relativistic calculations of the differential, integrated elastic, momentum transfer total cross sections and spin polarization parameters for positrons scattered from Gold atom using a simple optical model potential to represent interaction between positron and target atoms in the energy range 2.0-500eV. In the present calculation we employ a parameter-free model potential for the correlation polarization and absorption potential as devised for positron-atom scattering. The theoretical results are obtained from relativistic approach based on solving the Dirac equation using Hartree-Fock and Dirac-Fock wave functions.
