Title: Polarisation Potential Models for Positron scattering from bound atoms Authors: Nithyanandan Natchimuthu and Kuru Ratnavelu Affliations: Institute of Mathematical Sciences University of Malaya 50603 Kuala Lumpur, MALAYSIA Summary: In general, optical potential methods used to study positron scattering from atoms utilised semi-empirical treatments of the polarisation potentials. In this work, we have tested a number of these potential models for positron scattering from bound atoms
