A thorough grasp of the figures in this chapter is absolutely essential for any understanding of the CBED technique. Experience shows that few electron microscopists unde

We then specialize to the two-beam case, which provides the quickest and most useful guide to CBED intensity distributions. However, the study of non-centrosymmetric crystals requires the three-beam theory, so this is also treated. Both nondegenerate and degen

Historicization and Historicismer than the Bragg angle. These methods have been reviewed by Vincent (1989). Such an angular expansion is required for space-group determination of crystals with a large unit cell, in which overlap of low orders may occur at such a small illumination angle θ. that little or no rocking-curve structur

rom nanometer-sized regions of crystal, the method has proven extremely useful, in combination with X-ray microanalysis, for identifying microphases in multiphase materials, and for the study of the symmetry changes which accompany phase transitions (Ecob ., 1981b).
