Dynamical Theory of X-Ray Diffraction for Restricted Beams: I. Coherent Scattering by a Porous Crystal

Аннотация

A dynamical theory of X-ray coherent scattering of spatially restricted beams in porous crystals has been developed. The solutions have been obtained for the amplitude transmission and reflection coefficients as functions of the beam size and structural characteristics of the crystal. The peculiarities of the formation of reciprocal space maps as well as vertical and transverse cross sections of coherent scattering by porous films, gradient structures, and superlattices have been demonstrated.
