Phase identification of single crystals using a self-consistent indexing scheme based on the Laue method

The application of the Laue method is extended to phase identification of single crystals. This extension is made possible by a new method of indexing Laue patterns, which is based on computerized rotation of the reciprocal axes of the crystal and a new criterion for judging true solutions. The new method and criterion have been tested successfully for crystals with various structures, including triclinic. An example is given for the phase identification of molybdenum oxide which has six structural modifications.
