| Abstract: | We propose a new exactly solvable potential which is formed by
modified Kratzer potential plus a new ring-shaped potential
ηcot2θ/r2. The solutions of the Dirac equation with
equal scalar and vector ring-shaped modified Kratzer potential are
found by using the Nikiforov-Uvarov method. The nonrelativistic
limit of the energy spectrum has been discussed. |
