Abstract
The representations of point groups appropriate to spin-12 particles is usually determined by consideration of a group of double the order of the point group under consideration, known as the double group. An alternative approach is described which makes use of ray representations. The character tables for the 32 crystallographic point groups are derived simply by means of this approach.Keywords
