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.
