Abstract. The analytical expressions for the energy eigenvalues and eigenfunctions are computed for Coulomb perturbed potential by solving the Schrodinger equation within the framework of the Nikiforov-Uvarov functional analysis method and applying the Greene-Aldrich approximation. Using the energy eigenvalue expression, we have determined the mass spectra of cs ̅ and b ̅c mesons. The results of present study are in good agreement with experimental, relativistic and other relevant works available in the literature.
