Expressions for the dynamical Krivoglaz—Debye—Waller factor with taking into account the dispersion mechanism of defects’ influence on the multiple-scattering pattern are obtained. An essential distinction between the dynamical and kinematical factors is shown that is important to take into account for construction of self-consistent dynamical scattering theory. Dependence of the dynamical factor on diffraction conditions is ascertained. This dependence causes additional influence of diffraction conditions on the character of the scattering-pattern dependence on defect types in a crystal. An account of this influence allows to separate quantitatively and adequately the defects’ contribution to the intensity and, correspondingly, substantially improve the informativity and reliability of diagnostics.

Key words: Krivoglaz–Debye–Waller factor, dispersion mechanism, dynamical diffraction.
