Abstract

In the work we have considered the reduction techniques matrix element of the reaction interaction of elementary particles for massive fermions to spinor products . The our procedure is not more complex than CALCUL spinor techniques for massless fermions. It is relatively simple and leads to basic spinor products with any polarizationod fermions. Also obtained spinor Chisholm identities for massive fermions.
