Abstract

The approximate analytical solutions of the Dirac equation with the Poschl-Teller potential is presented for arbitrary spin-orbit quantum number kappa within the framework of the spin symmetry concept. The energy eigenvalues and the corresponding two Dirac spinors are obtained approximately in closed forms. The limiting cases of the energy eigenvalues and the two Dirac spinors are briefly discussed.
