In this paper we review experiments carried out at Cornell University in recent years concerning fine structure in core edges and effects in cross sections that relate to orientation dependent effects on inelastic electron scattering in crystals. The experiments are primarily of an exploratory character but do demonstrate how inelastic scattering could be of value in studies of oxidation in transition metals. They also indicate how characteristics such as the directionality of a final state Π* orbital or peaks in the final density-of-states appear in the spectra. Finally, at low energy losses the orientation dependence can be related to anisotropic effects in the optical constants.The experiments were carried out in a Hitachi HU-llA-Wien electron spectrometer system described previously. For present purposes, the role of the electron microscope is to provide a sophisticated electron optical bench which, using small angle scattering geometry, can explore scattering angles below 3x10-4 radians at angular resolutions of 10-5 radians (corresponding to a wave vector change of k0θ≃0.0015 Å-1).
