摘要：
An approach to the study of the mosaic structure of single crystals (exempli fled by fluorite) by the joint use of x-ray diffractometry and topography is proposed. Using a numerical simulation technique for angular distribution of the diffuse background in the region of a Bragg peak and various models of microscopic defects, it is established that the best-suited model for description of structural imperfections in individual mosaic blocks is a model of random distribution of microscopic blocks in the crystal bulk. The size of mosaic blocks and their misorientation and boundary type are studied.
