摘要：
In this Letter. the Dirac equation is exactly solved for spatially-dependent mass Coulomb potential including a Coulomb-like tensor potential under pseudospin symmetry limit by using asymptotic iteration method with arbitrary spin-orbit coupling number kappa. The energy eigenvalues and corresponding eigen-functions are obtained and some numerical results are given. (c) 2010 Elsevier B.V. All rights reserved.
