Abstract

A spectrometer for two-electron coincidence spectroscopy of solid surfaces in back-reflection geometry ((e,2e) spectroscopy) is described. The combination of the coincidence technique with time-of-flight electron energy measurements enables implementation of a “complete scattering experiment” on a solid surface, where the momenta of the incident and two scattered electrons are determined. The contributions of single-step and multi-step scattering events to the emission of two time-correlated electrons can be separated on the basis of experimental geometry and kinematics. Examples of applications of (e,2e) scattering to the study of various surface phenomena and electron scattering dynamics are presented.
