Abstract

We study the Dirac equation with scalar and vector Manning-Rosen potentials and a Hulthén tensor term in the pseudospin and spin symmetry limits. The energy eigenvalues and the corresponding upper- and lower-spinor wave functions are obtained using the Nikiforov-Uvarov (NU) method and proper approximations for any spin-orbit coupling term κ. Some numerical results of the energy eigenvalues equations and the upper- and lower-spinor wave functions are included to reveal the effect of the tensor interaction on the system.
