DP - 1970 Jan 01, TA - Oriental Journal Of Physical Science PG - 03-09 VI - 7 IP - 8 4099 - orientaljphysicalsciences.org/article/49/ 4100 - orientaljphysicalsciences.org/article/49/ AB - An exact analytical and approximate solution of the relativistic and non-relativistic wave equations for central potentials has attracted enormous interest in recent years. By using the basic Nikiforov-Uvarov quantum mechanical concepts and formalism, the energy eigenvalue equations and the corresponding wave functions of the Klein–Gordon and Schrodinger equations with the interaction of Modified Hylleraas-Hulthen Potentials (MHHP) were obtained using the conventional Pekeris-type approximation scheme to the orbital centrifugal term. The corresponding unnormalized eigen functions are evaluated in terms of Jacobi polynomials.
