Abstract
The method of energy analysis of back-scattered electrons has been applied in studies of single crystal surfaces of tungsten, graphite and copper for primary electrons in the range of 30–350 eV. The information that is obtained by this method on the various inelastic processes, coupled with LEED patterns from the same surfaces, provides additional understanding of the scattering of electrons in the low energy range. The identification of peaks in energy distribution curves due to the excitation of bulk and surface plasma resonances in tungsten is made. The energy distributions for all three materials show additional features attributable to single electron interband transitions and Auger transitions. For copper the energy loss measurements are correlated with the optical reflectivity data of Ehrenreich and Philipp.
