Abstract
The solutions of the klein-gordon equation with Manning-Rosen plus Yukawa potential (MRYP) has been presented using the Pekeris-like approximation of the coulomb term and parametric Nikiforov-Uvarov (NU) method. The bound state energy eigenvalues and the corresponding un-normalized eigen functions were obtained in terms of Jacobi polynomials. So also, Yukawa, Manning-Rosen and coulomb potentials have been recovered from the mixed potentials and their eigen values obtained.
Keywords: Klein-gordon equation, Manning-Rosen potential, Yukawa potential, Pekeris-like approximation, parametric Nikiforov-Uvarov method, Jacobi polynomials
