【 摘 要 】

Romanovski Polynomial method was used to analyze D-dimensional Dirac equation with Eckart plus Hulthen central potential coupled by modified Yukawa tensor potential in the case of spin symmetry and pseudospin symmetry. 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 D- dimensional relativistic energy are obtained from D-dimensional relativistic energy equation by using Matlab R2008b software. The relativistic energy spectra with dimensional variation were obtained.
