Automated determination of the extinction symbol via electron diffraction data

Abstract

The identification of the extinction symbol is routine for single-crystal X-raydata. Because of peak overlap and possible preferred orientation the task ismore difficult for powder diffraction data, but recent computer programs basedon probabilistic approaches have made it more automatic. This paper describesa new algorithm for the automatic identification of the Laue group and of theextinction symbol from electron diffraction intensities. The algorithm has astatistical basis and tries to deal with the severe problems arising from the oftennonkinematical nature of the diffraction intensities and from the limitedaccuracy of the lattice parameters determined via electron diffraction. Theapproach has been checked using a wide set of test structures.
