Solution of generalized Dirac equation for Eckart plus Hulthen central potential combined with modified Hylleraas like tensor potential using Romanovski polynomial method

Romanovski Polynomial method was used to analyze of Dirac equation with Eckart plus Hulthen central potential combined with modified Hylleraas like tensor potential on spin symmetry case. By using parameter and variable substitution, the Dirac equation was reduced into one dimensional Schrodinger like equation with centrifugal approximation that can be solved using Romanovski polynomial The relativistic energy spectra is obtained from the relativistic energy equation by using Matlab R2008b software. The relativistic energy with quantum number and spin orbit quantum number variations were obtained. By using matlab R2008b software, visualisasion of the relativistic energy spectra with quantum number variasion were obtained.
