Many-center Coulomb Sturmians and Shibuya-Wulfman integrals

Abstract

When momentum space is projected onto the surface of a unit 4-D hypersphere by means of Fock's mapping, Coulomb Sturmian basis functions can be simply represented in terms of hyperspherical harmonics. The properties of these harmonics can be used to evaluate Shibuya-Wulfman integrals and other integrals that arise when the Sturmian basis functions are used in molecular calculations. © 2003 Wiley Periodicals, Inc.
