Low-energy electron scattering from xenon

A detailed experimental and theoretical study of elastic electron-xenon scattering has been carried out for incident electron energies between 0.67 and 50 eV. The experimental measurements have been conducted using a crossed-beam apparatus and the relative flow technique, while the theoretical calculations are a fully relativistic treatment which also includes the effects of polarization and dynamic distortion. The experimental results (absolute differential cross sections) have been analysed with a relativistic version of a phase-shift analysis program in an effort to extract the low-order phase shifts, including the two spin-orbit components of the low-energy p-wave phase shift, and to derive the total elastic and elastic momentum transfer cross sections. Extensive comparisons between the present measurements and calculations and previous experiment and theory are provided.
