Abstract

We obtain the bound state energy eigenvalues and the corresponding wave functions of the Dirac particle for the generalized Hulthen potential plus a ring-shaped potential with pseudospin and spin symmetry. The Nikiforov{Uvarov method is used in the calcula-tions. Contribution of the angle-dependent part of the potential to the relativistic energy spectra are investigated. In addition, it is shown that the obtained results coincide with those available in the literature. © World Scientific Publishing Company.
