Abstract

A general potential for which the one-dimensional Schrödinger equation is solvable in terms of hypergeometric functions is considered. Properties of Jost functions and of the S-matrix are investigated for vanishing angular momentum. The Green function of the problem is constructed for the limiting case corresponding to a confluent hypergeometric equation. The potential with a Coulomb asymptotic at infinity — a generalization of the ordinary Coulomb potential — is analyzed with particular detail.
