  The BES collaboration has recently observed a strong enhancement close to the
proton-antiproton threshold in the J/Psi decays into photon, proton and
antiproton. Such a structure can be explained by a traditional
nucleon-antinucleon model. The near threshold 1S0 bound state and/or the
well-established 3P0 resonant state found in this nucleon-antinucleon
interaction can adequately describe the BES data.
