Title : Recursive technique for calculation Feynman diagrams
Authors : Victor Andreev

Abstract : 
A method is presented in which matrix elements for some processes are
calculated recursively. This recursive calculational technique based on
the method of basis spinor, which related with isotropic tetrad in
Minkowski space.  This method can be easily realized in the systems of
symbolic calculations (Mathematica, Maple, Reduce). As an example, we
obtained the amplitudes of interaction processes $e^-e^+\to n \gamma}$
with the help of the simple rule-based program in environment
Mathematica.
