Abstract
Dynamical X ray scattering in crystals modulated by an acoustic wave has been consistently considered. Diffraction in the cases of a spatially uniform amplitude of ultrasound in the crystal bulk and a surface Rayleigh wave has been investigated. It has been shown that the diffraction order profiles for a homogeneous acoustic wave correspond to the traditional Bragg peaks. The splitting of different diffraction maxima for large amplitudes of the surface acoustic wave has been observed. This splitting is caused by the X ray interference that is due to variations of elastic strains from the surface to the bulk of the crystal.
