Approximate analytical versus numerical solutions of Schrödinger equation under molecular Hua potential



We solve the D-dimensional Schrödinger equation under the Hua potential by using a Pekeris-type approximation and the supersymmetry quantum mechanics. The reliability of the spectrum is checked via a comparison with the finite difference method. This interaction resembles Eckart, Morse, and Manning–Rosen potentials. Some useful quantities are reported via the Hellmann–Feynman Theorem. © 2012 Wiley Periodicals, Inc.
