Bound State Solutions of the Klein Gordon Equation with the Hulthén Potential

Abstract: An approximate solution of the Klein–Gordon equation for the Hulthén potential with equal scalar and vector potential is presented. Using the new improved approximation scheme to deal with the centrifugal term, we solve approximately the Klein–Gordon equation via the Nikiforov–Uvarov method for an arbitrary angular momentum quantum number. The corresponding eigen – energy and eigen functions are also obtained for the s-wave bound state
