THE CALCULATION OF ELECTRON DIFFRACTION PATTERNS CONTAINING TWIN REFLECTIONS

Abstract

The positions of twin reflections in electron diffraction patterns obtained from thin metal foils may be calculated for any twin in any crystal structure by means of an elementary application of vector algebra. General equations for the four classical orientation relationships are presented using the superscript and subscript notation of the tensor calculus, which is briefly described. As an example of the application of these expressions, the case of twinned rhombohedral crystals, and hence as a special case, twinned cubic crystals, is examined.
