Elastice±-Ar scattering with the use of the model potential method

Abstract
A model-potential method due to Khan et al. [Phys. Rev. A 29, 3129 (1984)] is used to investigate elastic e±-Ar scattering at low incident energy, up to 18 eV. The effect of short-range correlation has been included via an adjustable parameter. Same polarization potentials have been used for both the electron and positron cases, and scattering parameters are presented. The results are found to be in good agreement with the existing theoretical predictions and measured values.
