Analytical evaluation of multicenter integrals for Slater-type orbitals. II. Three-center nuclear attraction integrals

Abstract

Convenient formulas have been obtained for three-center nuclear attraction integrals with an arbitrary combination of quantum numbers of Slater-type atomic orbitals. New auxiliary functions have been introduced by means of which these integrals are expressed. The auxiliary functions are discussed in detail, and recurrence relations and analytical formulas given for their computation.
