The relativistic approach to p¯-nucleus interactions is extended to p¯-atom interactions. Both the relativistic impulse approximation and Dirac phenomenology are used to obtain low energy p¯-nucleus potentials. The impulse approximation is qualitatively successful at describing the p¯-atom data. For ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, potentials fit to the 46.8 MeV data yield the experimental shifts and widths well within the assigned errors.
