Spin Symmetry in Dirac-Attractive Radial Problem and Tensor Potential

In this paper, we solve the Dirac equation under spin symmetry limit for attractive radial potential including a Coulomb-like tensor interaction. By using the parametric generalization of the Nikiforov-Uvarov method, the energy eigenvalues equation and the corresponding wave functions have been obta...

Description
Summary:In this paper, we solve the Dirac equation under spin symmetry limit for attractive radial potential including a Coulomb-like tensor interaction. By using the parametric generalization of the Nikiforov-Uvarov method, the energy eigenvalues equation and the corresponding wave functions have been obtained in closed forms. Some numerical results are given too.
