Calculation of QED graphs with the spinor technique

Abstract QED tree diagrams are calculated with the spinor technique using symbolic algebra. A first program SPINORP1 calculates all topologically distinct diagrams. The input are the number and kinds of particles. A second program SPINORP2 generates a REDUCE source program to evaluate the spinor amplitude for all possible polarizations of the external particles.
