In this paper the Dirac equation is analytically solved for Coulomb plus a novel angle-dependent potential. The Nikiforov–Uvarov method is used to obtain energy eigenvalues and corresponding eigenfunctions. We also discussed the effect of the angle-dependent part on radial solutions.
Key words: Dirac Equation; Coulomb Potential; Novel Angle-Dependent Potential; Nikiforov–Uvarov Method.
