Powder and related techniques: electron and neutron techniques International Tables for Crystallography (2006). Vol. C, ch. 2.4, pp. 80-83 [ doi:10.1107/97809553602060000579 ] Abstract In the first part of this chapter, methods for obtaining powder diffraction patterns using electron microscopy are described. The effects of preferred orientation are considered and the kinematical and two-beam approximations for the intensities of electron diffraction are described. Factors that have to be considered when using powder electron diffraction techniques for crystal-size analysis and the identification of unknown phases are noted. In the second part of the chapter, powder neutron diffraction is described. Advantages of powder neutron diffraction include the ability to collect data from samples at high or low temperatures or as a function of pressure. The different types of diffractometer in use are discussed and optimal experimental conditions for different kinds of experiments are considered. |
