The Interpretation and Application of Electron-Diffraction "Kikuchi-Line" Patterns - Part II. The Methods of Indexing the Patterns

Seven methods are described of indexing electron-diffraction Kikuchi-line patterns from single crystals for the purpose of practical applications of such patterns. The crystal lattice form and orientation can be determined by method 1 (see Part I), which also gives the indices of the diffractions relative to the chosen unit cell. The other six methods are in general only applicable in conjunction with a knowledge of the crystal lattice form and orientation, in which case any one of them, or more conveniently several in conjunction, can be used to index the lines.
