Spin Symmetric Solutions in Central Field Including Tensor Interaction

For any spin-orbit quantum number k, we present the bound state solutions of the Dirac equation with Hulthen plus a class of Yukawa potential in the presence of a Coulomb-like tensor interaction under spin symmetry limit. We construct relativistic energy spectrum and the radial wavefunction by means of asymptotic iteration approach in approximate analytic form. By applying a developed scheme which is based on Greene Aldrich approximation, we cope with the centrifugal term. We investigate the effect of tensor potential on spin doublets. We report special cases of a combination of Hulthen potential and a class of Yukawa potential such as Hulthen, Yukawa, inversely quadratic Yukawa potentials.
