The defect structure of crystalline compounds is investigated using the total integrated-reflectivity method. For interpretation of the experimental data, a generalized dynamical theory of x-ray diffraction is applied to real crystals containing randomly distributed microdefects of various types and a disturbed surface layer. The dynamics of the concentration and size variations are analysed for several types of interconnected dominant defects, including spherical and disk-shaped clusters, as well as dislocation loops.

Key words: total integrated reflectivity, high-resolution x-ray diffractometry, dynamical theory, kinematical theory, diffraction curves, crystalline compounds.
