Abstract
We have calculated the phase shifts, differential cross sections (DCS’s), total cross sections (TCS’s) and momentum transfer cross sections (MTCS’s) for the positrons scattered elastically from Ne, Ar, Kr and Xe atoms. The theoretical method is based on combining the static potential with the polarisation potential (containing both dipole and quadrupole polarisabilities) at long distances and with the correlation potential of Ashok Jain at short distances. We found a good general agreement with other experimental and theoretical values of many investigators.
