Structure factor for a Bragg diffraction maximum. Effect of temperature vibration on diffraction pattern. Integrated intensity for a small crystal and for a crystalline powder-polycrystal. Diffraction by a crystalline powder. Diffractometer recording of diffraction pattern and collecting of diffraction data. Instruments for high and low temperature, high pressure and controlled atmosphere. New trends in development of diffraction instruments. Synchrotron radiation. Diffraction of electrons and neutrons by a crystalline powder. Analysis of systematic and random errors in measurement of diffraction maximum position. Identification of a crystalline material, qualitative and quantitative phase analysis. Accurate measurement of unit-cell parameters. Study of order-disorder in a crystal lattice. Diffraction by a defect crystal. Broadening of diffraction maxima. Determination of pure diffraction profile. Selection of mathematical functions describing a diffraction profile. Crystallite size and lattice imperfections (strains). Faults in sequence of crystal-lattice plains. Study of solid solutions, phase transitions and phase diagrams. New methods in indexing of diffraction pattern of a polycrystal and solution of crystal structure. Strategies for structure solution from powder diffraction data.
