Differential cross sections for positron-xenon elastic scattering

Marler, Joan P; Surko, Clifford M; McEachran, Robert; Stauffer, A D

Description

Absolute measurements of differential cross sections for the elastic scattering of positrons from xenon are made at 2, 5 and 8 eV using a trap-based beam and the technique of measuring scattering cross sections in a strong magnetic field. Calculations are carried out using the relativistic Dirac equations with a static plus polarization potential. Generally good absolute agreement is found between experiment and theory.
