Title of program: F3Y Catalogue Id: AAQQ_v1_0 Nature of problem First-principles calculations on atoms and molecules usually express the many-body wave function psi in terms one-particle states of the form phi(r) = Rnl(r)Ylm(theta, phi), and the evaluation of physical quantities form psi invariably requires a considerable amount of manipulation of the Ylm(theta, phi). Integrals of products of spherical harmonics appear in the evaluation of Coulomb matrix elements in atomic calculations and they are closely related to the addition of angular momenta. We there ...
