Dirac particles in the field of Frost-Musulin diatomic potential and the thermodynamic properties via parametric Nikiforov-Uvarov method

The Frost-Musulin Diatomic molecular potential has been investigated under spin and pseudospin symmetries of the Dirac equation in a comparative study. By using a siutable approximation scheme, we have presented the energy eigenvalues for both the spin symmetry and pseudospin symmetry and the corresponding upper and lower spinor component of the wave functions in a close form. We have obtained the non-relativistic limit and compared our numerical eigenvalues with the one previousely obtained. Finally, we calculated thermodynamic properties of a particle under the Frost-Musulin diatomic potential.
