Low energy positron scattering from neon atoms

Abstract

Further study of a physically motivated, parameter-free approximation used in calculating positron-atom and positron-molecule polarization potentials is made. The method mimics the effects of virtual positronium formation at low scattering energies in the near target region and reduces to the correct adiabatic result as the positron recedes from the target. This thesis describes a specific application of the model to positron-neon scattering.
