In this paper, we study the Dirac equation with a multiparameter exponential-type potentialincluding two tensor interactions. We obtain the energy eigenvalues by using the Nikiforov-Uvarovmethod. The corresponding wave functions are obtained and expressed in terms of hypergeometricfunctions. The effects of the Coulomb and the Yukawa tensor interactions are also investigatednumerically and discussed in detail.
Relativistic Symmetries in the Dirac Equation for an Eight-parameter Exponential-type Potential

Applying the Pekeris approximation to the centrifugal term, we investigated the spin and pseudospin symmetric solutions of the Dirac equation for $an$ eight-parameter exponential-type potential with a Coulomb-like tensor interaction. The energy eigenvalue equation and the corresponding eigenfunction are obtained using the Nikiforov-Uvarov (NU) method. The effects of the Coulomb tensor interaction are investigated numerically.
