Space-Group Selection Rules: "Rocksalt"Oh5−Fm3m

Abstract

Complete tables of reduction coefficients for ordinary products, and symmetrized squares and cubes of representations in "rocksalt" structure ${O_h}^5-\mathrm{Fm}3m$ are presented. These have all been obtained by using the full-group method. These coefficients are useful for obtaining selection rules and lattice invariants and covariants for this structure. An illustrative example demonstrates the ease and convenience, as well as the completeness, of carrying out full-group calculations.
