Low-energy elastic and inelastic scattering of positrons from argon

Abstract

Absolute measurements of elastic differential cross sections for positron scattering from argon at energies from 2-50 eV are presented as well as total elastic and total inelastic cross sections from 2-20 eV. Comparisons of the current data, previous experimental data, and theoretical models using the convergent close-coupling and relativistic optical potential methods are made.
