摘要
Approximate analytical bound-state solutions of the Dirac particle in the fields of attractive and repulsive Rosen–Morse （RM） potentials including the Coulomb-like tensor （CLT） potential are obtained for arbitrary spin–orbit quantum number κ. The Pekeris approximation is used to deal with the spin–orbit coupling terms κ（κ ± 1）r 2 . In the presence of exact spin and pseudospin （p-spin） symmetries, the energy eigenvalues and the corresponding normalized two-component wave functions are found by using the parametric generalization of the Nikiforov–Uvarov （NU） method. The numerical results show that the CLT interaction removes degeneracies between the spin and p-spin state doublets.
