Title of program: WEIGHTS Catalogue Id: ACQL_v1_0 Nature of problem In configuration interaction calculations, one wishes to evaluate the matrix of the Hamiltonian operator with respect to a basis set of configuration wave functions. The more difficult part of this procedure is the determination of the two-electron interaction matrix elements. These matrix elements may be written as a weighted sum of radial Slater integrals. The program calculates the coefficients of these integrals.
