Abstract

It has been found recently from the analysis of low-energy electron-transmission experiments that the scattering mean free path \ensuremath{\lambda} of excess hot electrons in solid xenon films oscillates with energy. We show in this paper that in these experiments \ensuremath{\lambda} is predominantly controlled by the combined effect of both acoustical-phonon scattering and scattering by neutral point defects, and that its energy dependence is entirely caused by the changes in electron effective mass with energy.
