Calculation of Many-Body Effects on Energy Distribution Curves in Photoemission

Abstract

A study of the energy distribution curves of photoemitted electrons from the simple metals is made. Several mechanisms responsible for producing photoemitted electrons are considered. In addition to the usual surface-ejection mechanism, we investigate the emission produced by the imaginary optical potential. Processes involving bulk and surface plasmons are studied. The contribution to the spectrum of low-energy secondary electrons arising from plasmons is estimated.
