• The results of the perturbation theory of the temperature diffuse scattering of electrons developed in the preceding paper are applied to practical problems with the assumption of two plane waves. It is shown that the intensity of the diffuse scattering does not become infinite at a reciprocal lattice point as it does in the current theory but remains finite, that the temperature diffuse scattering gives rise to Kikuchi patterns, and that the intensity of diffuse spots changes abruptly when the incident wave excites a Bragg reflexion. The anomalous intensity variation of the diffuse spots from the surface of some single crystals may be due to this effect. In the Bragg case the direction of the diffuse scattering can be obtained by the modified Ewald construction which replaces the Ewald sphere by the equi-energy surface in the reciprocal space. The possibility of treating the Kikuchi pattern due to the inelastical collision of incident electrons with lattice electrons by the present method is also discussed.
