摘要
We inquire into spin and pseudospin symmetries of Dirac equation under modified deformed Hylleraas and modified Eckart potential via a Pekeris approximation and the Nikiforov–Uvarov technique. A tensor interaction of Coulomb form is considered and its degeneracy-removing role is discussed in detail. The solutions are reported for arbitrary quantum number in a compact form and useful numerical data is included.
