Abstract
We consider the eigenvalue problem for the radial Schrödinger equation with potentials of the form where and are well behaved functions which tend to some (not necessarily equal) constants when and Formulas (14.4.5)–(14.4.8) of Abramowitz and Stegun [Handbook of Mathematical Functions, 8th ed. (Dover, New York, 1972)], corresponding to the pure Coulomb case, are here generalized for this distorted case. We also present a complete procedure for the numerical solution of the problem. Our procedure is robust, very economic and particularly suited for very large n. Numerical illustrations for n up to 2000 are given.
