Approximate solutions of the Klein–Gordon equation with unequal scalar and vector modified Hylleraas potential

Abstract

We have presented approximate solutions of the Klein–Gordon equation with unequal scalar and vector modified Hylleraas potential for arbitrary l-state. We have used the parametric generalization of the Nikiforov–Uvarov method to obtain the bound state energy eigenvalues and the corresponding wave function expressed in term of the Jacobi polynomials. We have also discussed two special cases of the potential.
