By using the Nikiforov–Uvarov (NU) method and a new approximation scheme to the centrifugal term, we obtained the solutions of the radial Schrödinger equation (SE) for the modified Rosen–Morse (mRM) potential. In this paper, we get the approximate energy eigenvalues and show that the results are in good agreement with those obtained before. Eigenfunctions are also presented for completeness.
Key words: Schrödinger Equation; Modified Rosen–Morse Potential; Nikiforov–Uvarov Method.
