Abstract
The shifted 1/N expansion technique is applied to the radial Dirac equ ation. it is shown that the fixing condition E(1) = 0 produces an enha nced accuracy for Yukawa and Hulthen potentials. The modified shifted 1/N expansion results are compared with the exact numerical results an d results obtained by other approximate methods.
