The following specialized blocks are integral parts of the subject: Detection of gamma rays and X-rays Detectors applied in nuclear experiments, basic principles and function, measurement of dose and dose rate, measurements under special conditions, detection setups and their geometry, signal analysis. X-ray crystal structure analysis Qualitative and quantitative phase analysis and structure determination by X-ray powder diffraction. Kinematic theory of diffraction, structure factor, space group, pair distribution function, phase problem, different diffraction experiments, phase analysis, crystallographic database, Rietveld analysis. Practical tasks: powder diffraction measurements, operation of powder diffractometer, sample preparation, in-situ experiments in reaction chamber, crystallographic database search, data evaluation. Scattering experiments in physics Classification of scattering experiments, elastic and inelastic scattering. One-dimensional scattering. Scattering in time and energy domain. Examples of scattering experiments: NMR, X-ray diffraction, inelastic scattering, Mössbauer spectroscopy, absorption spectroscopy.
