Tensor coupling and relativistic spin and pseudospin symmetries of the Po¨schl–Teller-like potential

In this research, we have been obtained the dirac equation for second po¨schl–teller-like potential including a coulomb-like tensor interaction with arbitrary spin–orbit coupling quantum number j. under the condi- tion of spin and pseudospin (p-spin) symmetries, we use the basic concept of the supersymmetric shape invariance formulism in quantum mechanics and the function analysis method to obtain energy eigenvalues and corresponding two-component spinors of the dirac particle. we have also shown that tensor interaction removes degeneracies between spin and p-spin doublets. some numerical results are also given.
