Inelastic Scattering of Fast Electrons by Crystals. II. The Excess and Defect Kikuchi Bands

Abstract

The intensity of the Kikuchi band is calculated as a function of crystal thickness, using the author’s theory (K. Ishida: J. Phys. Soc. Japan 28 (1970) 450.). In a thin crystal, the Kikuchi band appears as the excess (black) band and it changes to the defect (white) band as the thickness increases, in agreement with the experiments.
