PLO-04. Plan and perform experimental and / or theoretical research in physics (astronomy) and related interdisciplinary fields using modern tools, critically analyze the results of their own research and the results of other researchers in the context of the whole complex of modern knowledge on the research problem. PLO-07. Deeply understand the general principles and methods of natural sciences, as well as the methodology of scientific research, be able to apply them in their own research in physics (astronomy) and in teaching practice.

Distance form

1. Know the kinematic theory of X-ray scattering, general laws of crystal structure of bodies, Fourier analysis. 2. Be able to analyze and process the diffraction spectra of crystals, determine the type of crystal structure by diffraction spectra, analyze the results of Fourier transforms; 3. Possess basic skills of mathematical transformations, construction of algorithms, methods of approximation and methods of processing experimental results; fluent in the commonly used terms of the condensed state: crystal structure, near and far order, elastic and inelastic absorption, diffraction, structural type, coordination number, dimensional effects, etc.

The aim of the course is to get acquainted with the main types of disorder in the condensed state and to conduct a systematic review of X-ray diffraction on disordered structures with different types of ordering and gain practical skills in using diffraction methods to study disordered structures.
