A sorting and searching computer program to index electron diffraction patterns from crystals of low symmetry

Electron diffraction patterns generated from phases that have low crystallographic symmetry are difficult and tedious to analyze by conventional techniques. This paper describes a computation scheme that can index electron diffraction patterns efficiently and quickly and be easily implemented on a personal computer. The technique is based on sorting and searching and is especially useful when rapid analyses of electron diffraction patterns are necessary and the crystalline phase under study has a low symmetry.
