Complex angular momentum methods for elastic scattering with an optical potential

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.

问题性质
计算机程序REGGE旨在求解中心复势下的薛定谔方程的径向部分。它定位散射S矩阵在复角动量平面上的极点和零点，并计算极点的留数。据此获得的极点项与背景积分项相结合，在投影至物理（实整数）角动量空间后，用于计算截面。
