摘要：
The (3+1)-dimensional Dirac equation is solved in the presence of the radial pseudoscalar Hulthen potential by using the usual approximation of the centrifugal potential. The approach proposed by Biedenharn for the Dirac Coulomb problem is applied. Analytic bounded solutions of the Dirac equation with the pseudoscalar Hulthen potential are obtained in contrast to the pseudoscalar Coulomb one where there is no bounded solutions.
