Analytical solutions of the Schrödinger equation with the Manning-Rosen potential plus a Ring-Shaped like potential
The analytical solution of the Schrödinger equation for the Manning-Rosen potential plus a ring-shaped like potential is obtained by applying the Nikiforov-Uvarov method by using the improved approximation scheme to the centrifugal potential for arbitrary $l$ states. The energy levels are worked out and the corresponding normalized eigenfunctions are obtained in terms of orthogonal polynomials for arbitrary $l$ states.
