The grazing scattering by a crystal with subsurface dilatation-centre-type defects is investigated within the scope of the distorted wave Born approximation (DWBA) of the dynamical theory. The diffuse scattering cross-sections for Bragg diffraction from crystal planes perpendicular to the crystal surface are calculated. The impact of correlations between defects on the diffuse scattering pattern is analysed.

Key words: X-rays, grazing diffraction, dynamical theory, diffuse scattering, subsurface defects, correlation function.
