K-shell ionization under zone axis electron diffraction conditions

Technical Report:

Abstract

A comprehensive theoretical treatment for the inelastic scattering of fast electrons in a crystalline environment is applied to account for variations in characteristic x-ray emission rates from spinel and chromia under zone axis diffraction conditions for 300 keV electrons. X-ray counts as well as backscattered electron contrast are recorded as the beam is tilted by about 70 mrad on a two-dimensional scan raster. Calculated K-shell ionization and backscattering cross sections, based on a model which takes into account interaction delocalization, thermal diffuse scattering and the consequent thickness dependent channelling effects in a realistic way, are in good agreement with experiment. 43 refs., 13 figs.
