Abstract
The explicit form for the spin projection operators introduced by Fronsdal is calculated for arbitrary spin and applied to first-order processes involving four fermions. The matrix element for the most general nonderivative interaction is found for the special case in which two of the particles have spin ½. The method of relating matrix elements written in different orders is extended to this case.Keywords
