The Dirac equation inwith potentialis a relativistic field equation modeling the hydrogen atom. We analyze the singularity structure of the propagator for this equation, showing that the singularities of the Schwartz kernel of the propagator are along an expanding spherical wave away from rays that miss the potential singularity at the origin, but also may include an additional spherical wave ofdiffractedsingularities emanating from the origin. This diffracted wavefront isderivatives smoother than the main singularities, for alland is a conormal singularity.
