Abstract
The elastic scattering of positrons from noble gases has been formulated using a polarized-orbital approximation. In principle all multipole moments of the positron-atom interaction are included and the polarized orbital is calculated by a perturbed Hartree-Fock scheme. The scattered wave is readily obtained from a potential scattering problem and is used to calculate Zeff and the angular correlation as well as the scattering cross sections of interest. Numerical results are presented for positron-helium scattering in the elastic region.Keywords
