Abstract

The classical dynamical theory of X-ray diffraction is expanded to the special case of transversely restricted wavefronts of the incident and reflected waves. This approach allows one to simulate the two-dimensional coherently scattered intensity distribution centred around a particular reciprocal lattice vector in the so-called triple-crystal diffraction scheme. The effect of the diffractometer's instrumental function on X-ray diffraction data was studied.The dynamical theory of X-ray diffraction has been developed for spatially restricted beams. This approach allows one to calculate rocking curves as well as reciprocal space maps for both transmitted and reflected coherent wavefields.
