Relativistic Pseudospin and Spin Symmetries of the Energy-Dependent Yukawa Potential Including a Coulomb-Like Tensor Interaction

Section: Fields and elementary particles
Original Author's Text: English

Abstract: We solve the Dirac equation for the energy-dependent Yukawa potential including a tensor interaction term within the framework of the pseudospin and spin symmetry limits with arbitrary spin-orbit quantum number k. We obtained explicitly the energy eigenvalues and the corresponding wave function using the Nikiforov–Uvarov method. The limiting cases of this model are reduced to the energy-dependent Yukawa and Coulomb potentials, respectively.

Key words: Dirac equation, energy-dependent Yukawa potential, Nikiforov–Uvarov method.
