A general program for computing angular integrals of the Breit-Pauli Hamiltonian

Title of program: MCHF_BREIT Catalogue Id: ABZY_v1_0 Nature of problem In the Breit-Pauli LSJ approximation, the wave function is expanded in terms of configuration state functions with differing LS term values. To determine the coefficients in the expansion, the interaction matrix elements need to be expressed in terms of sums of radial integrals. This program calculates the coefficients of these integrals and produces a file INT.LST appropriate for input to the MCHF_CI program.
