Exact solutions to the Schrodinger equation for potentials containing Coulo
mb (similar to1/r) plus harmonic oscillator (similar tor(2)) terms are foun
d, subject to constraints on the ratio of the strengths of the Coulomb and
harmonic oscillator terms. The solutions have the simple form of a product
of exponential and polynomial functions. (C) 2001 Published by Elsevier Sci
