摘要：

Starting from an expression for the double-differential cross section for electron Compton scattering in a crystal for a two-beam case, valid for a small Ewald sphere, the contributions of M-shell and L-shell electrons in silicon to the mixed dynamic form factors are calculated. The shape and intensity of the interference effects that superimpose on the Compton profile are determined. It is shown that the appearance of interference terms renders the cross section asymmetric and dependent on the momentum transfer also in the usual momentum representation. A procedure for an experimental investigation of the interference terms is proposed.
