[en] Analytical bound and scattering state solutions of Dirac equation are investigated for the modified deformed Hylleraas potential with a Yukawa-type tensor interaction. The energy equation, phase shifts and normalization constants of the pseudospin and spin symmetry limits are represented. Since the modified deformed Hylleraas potential reduces to the Pöschl–Teller, Hulthén and deformed Hylleraas potential, energy equation and scattering properties of the Dirac equation for these potentials within a Yukawa-type tensor interaction has been obtained. Reported herewith is some numerical results to show the effect of tensor interaction
