In this paper, the energy eigenvalues and the corresponding spinors of the Dirac particles are obtained and the pseudospin symmetric solution of the attractive scalar and repulsive vector Morse potential for any spin-orbit quantum number. is provided by using the Pekeris approximation within the framework of the asymptotic iteration method.
