Abstract: A new technique for calculating the cross sections for binary reactions with polarized particles has been developed. The technique is based on direct calculation of matrix elements in a special form using the method of basis spinors. New analytical formulas for integrating differential cross sections with respect to the scattering angle of a binary reaction are presented.

Keywords: binary reaction, Feynman diagram, bispinor, helicity.
