    The recently introduced κ-Poincar e ́-Dirac equation is gauged to treat the κ-Dirac-Coulomb problem. For the resulting equation, we prove that the perturbation to first order in the quantum group parameter vanishes identically. The second order perturbation is singular, but assuming a heuristic cut-off allows a qualitative estimate of the quantum group parameter. © 1993.
