Abstract

The analytical bound state solutions of the Dirac equation for the Manning-Rosen potential are carried out by a new proper approximation to the spin-orbit coupling term. The energy spectrum formula and the corresponding two-component spinor wave functions of the Dirac equation are obtained for the application of the Supersymmetric Quantum Mechanics (SUSYQM). We study three special cases; the general s -wave problem, spin symmetry and pseudospin symmetry.
