Abstract
X-ray diffraction in a crystal with lattice strains is studied theoretically using two-dimensional recurrence relations in Laue geometry. Based on these relations, an algorithm for calculating the coherent scattering intensity near a reciprocal-lattice node is developed. Simulation of reciprocal-space mapping was performed for a model of a silicon crystal with Si(Al) thermomigration channels. The change in reciprocal-space maps is shown depending on the strain magnitude in the channel and scanning of the X-ray beam along the input surface of the crystal.
期刊介绍：
Many research topics in condensed matter research, materials science and the life sciences make use of crystallographic methods to study crystalline and non-crystalline matter with neutrons, X-rays and electrons. Articles published in the Journal of Applied Crystallography focus on these methods and their use in identifying structural and diffusion-controlled phase transformations, structure-property relationships, structural changes of defects, interfaces and surfaces, etc. Developments of instrumentation and crystallographic apparatus, theory and interpretation, numerical analysis and other related subjects are also covered. The journal is the primary place where crystallographic computer program information is published.
