Abstract: A technique for calculating matrix elements of elementary particles interaction reactions using the “building” blocks (basic elements of Feynman diagrams) method is presented. In this approach, the matrix element is reduced to basic matrix elements involving basis spinors. Such blocks are calculated in advance using the Method of Basis Spinors (MBS) and then used for further calculations.

Keywords: basis spinor, Feynman diagram, Dirac matrix, fermion.
