## Abstract We propose a common description of the full widths at half maximum of X‐ray diffraction peaks obtained in different scans of triple‐crystal diffractometry and as well as for glancing incidence and glancing exit double‐crystal measurements. Calculations are compared with measurements of

## Abstract The X‐ray diffraction peak profiles due to misfit dislocations are studied for the dislocations correlated on distances much smaller than the film thickness. Simple analytical expressions for the correlation parameter are obtained when the dislocations are generated as a Markov chain. M
The theory of kinematic X-ray diffraction from dislocated crystals as developed in [l] is extended to crystals containing more than one set of straight parallel dislocations. The Bragg reflexion line broadening is expressed by two parameters of the dislocated cryst,al, the dislocation density, e, an
