Atomic and nuclear complex energy (Gamow) states of the p-barp system are calculated with the Graz potential. The Coulomb force is included exactly (numerically), separate channels and experimental masses are used for p-barp and n-barn, and absorption is included via a phenomenological annihilation channel. Significant model dependence of the n = 1 /sup 1/S/sub 0/ protonium level is found, as is a possible systematic difference among most calculations and recent experiments. Bound and resonant states of baryonium are found in a number of charge and isospin channels, some with widths as narrow as 16 MeV. Unphysical zero width states are also found and analyzed.
