Bound State Solutions of the Klein-Gordon Equation for Rosen-Morse Potential in Spin and Pseudo-Spin Symmetry

In this article, the bound state solutions of the Klein-Gordon equation for Rosen-Morse potential with mixed scalar-vector potentials are investigated within the framework of spin and pseudo-spin symmetric limits. It is also explained that the bound state energy spectrum exists only for the spin symmetric limit, but not for the pseudo-spin symmetric limit. To pursue the investigation the asymptotic iteration method is used. My results are in excellent agreement with previous work.
