Exact solutions of the D-dimensional Schrödinger equation for a ring-shaped pseudoharmonic potential

Abstract

A new non-central potential, consisting of a pseudoharmonic potential plus another recently proposed ring-shaped potential, is solved. It has the form V(r,θ) = 1/8κre2 (r/re - r/re)2 + βcos2 θ/r2sin2θ. The energy eigenvalues and eigenfunctions of the bound-states for the Schrödinger equation in D-dimensions for this potential are obtained analytically by using the Nikiforov-Uvarov method. The radial and angular parts of the wave functions are obtained in terms of orthogonal Laguerre and Jacobi polynomials. We also find that the energy of the particle and the wave functions reduce to the energy and the wave functions of the bound-states in three dimensions. © Versita Warsaw and Springer-Verlag Berlin Heidelberg 2008.
