Computer generation of Feynman diagrams for perturbation theory II. Program description

Title of program: P.T. DIAGRAM GENERATION Catalogue Id: AAKH_v1_0 Nature of problem Program finds pertinent topologically distinct diagrams of the Hugenholtz type, which are necessary in calculations of correlation energies, ionization potentials and electron affinities, excitation energies and double ionization processes using the field theoretical form of the perturbation theory.
