Double-valued Corepresentations of Magnetic Point Groups

Abstract

The theory of the corepresentations of non-unitary groups, which was developed by Wigner, is applied here to the determination of the double-valued corepresentations of the magnetic point groups. Complete tables are given for the double-valued corepresentations of each of the 58 magnetic point groups. A comparison is made with previous work by Dimmock and Wheeler.
