# A Pascal program for calculating the reduced Coulomb Green's functions and their partial waves

## Description

Title of program: RCGF Catalogue Id: ACEP_v1_0 Nature of problem The reduced Coulomb Green's function is the coordinate space representation of the sum over intermediate states encountered in bound state second order perturbation theory. This function does not depend on the particular perturbation problem. Thus, it is useful to have it calculated once. When the perturbation Hamiltonian is decomposed into terms of definite angular momentum it is useful to have the partial waves of the Green's function. We therefore present a program for calculating the functio ...
