The Kikuchi patterns of Mo{100} obtained in the incident electron energy range 0.5–2 keV have been compared with the angular distributions of electrons scattered quasielastically from polycrystalline molybdenum. The principal maxima of electron emission from Mo{100} are shown to correspond to the outgoing electrons oriented along closely packed atomic rows. For fixed polar angles θ, the electron emission intensity at the maxima may exceed by 3–4 times that at the minima. The average contrast of the Kikuchi patterns (with exception of the high symmetry orientations) varies only slightly over the θ angle range studied, 20–80°. The observed enhanced electron emission from a single crystal compared with a polycrystalline sample drops off with increasing polar angle. A study of the effect of crystal temperature on the angular distributions of quasielastically scattered electrons has shown an increase of temperature to reduce primary the emission at the maxima. The major results of the study are qualitatively accounted for the effect of primary electron localization on the secondary diffraction of quasielastically scattered electrons.
