Exact Spin and Pseudo-Spin Symmetric Solutions of the Dirac-Kratzer
Problem with a tensor potential via Laplace Transform Approach

Altug Arda, Ramazan Sever
Exact bound state solutions of the Dirac equation for the Kratzer potential in the presence of a tensor potential are studied by using the Laplace transform approach for the cases of spin- and pseudo-spin symmetry. The energy spectra is obtained in the closed form for the relativistic as well as non-relativistic cases including the Coulomb potential. It is seen that our analytical results are in agrement with the ones given in literature. The numerical results are also given in a table for different parameter values.
