In their recent paper (Inter. J. Mod. Phys. A 26 (2011) 1011), Zarrinkamarand coauthors have considered the radial Dirac equation for a Coulomb scalar,vector and tensor interaction. The exact solutions for the energy eigenvaluesthey have reported for spin-symmetry and pseudo-spin symmetry were mishandledand are incorrect eigenvalues, therefore.
