Title of program: REGGE Catalogue Id: ABNF_v1_0 Nature of problem The computer program REGGE solves the radial part of the Schrodinger equation for a central complex potential. It locates the poles and zeros of the scattering S-matrix in a complex angular momentum plane, and also computes the residues of the poles. The pole terms thus obtained are combined with the background integral term and the sum, after being projected on to physical (real integer) angular momentum space, is used to calculate cross sections.
