Notes:
For X-ray diffraction by a pure low-angle twist boundary perpendicular to a crystal surface, within the framework of the kinematic and dynamical theories, the following integral characteristics are calculated: (a) the bicrystal reflectivity in the vicinity of the lth reflection; (b) the integrated intensity of the lth reflection; (c) the bicrystal total reflectivity, i.e. the sum of the integrated intensities over all reflections. The case for even h. b (b is the diffraction vector, b is the Burgers vector of the boundary screw dislocations) is considered. In dynamical theory an increase of the total reflectivity of a bicrystal due to the boundary dislocation structure is obtained.
