WebClassical theory of crystals reduces crystals to point lattices where each point is the center of mass of one of the identical units of the crystal. The structure of crystals can be analyzed by defining an associated group. Webbeam divergence and the crystal mosaic distribution. It should be noted that length scales are not respected (H b and H f << L MS sinθ). As an example, some typical values are reported in table 1. The gain in beam compression has been estimated for a Bragg angle of 30°, a mosaic β of 0.1° and for crystal heights of 10 mm and 30 mm.
