A relativistic particle in an attractive Coulomb field as well as a staticand spherically symmetric gravitational field is studied. The gravitationalfield is treated perturbatively and the energy levels are obtained for bothspin 0 (Klein-Gordon) and spin 1/2 (Dirac) particles. The results are shown tocoincide with each other as well as the result of the nonrelativistic(Schrodinger) equation in the nonrelativistic limit.
