英文摘要	Based on 7.8 million J/psi, events collected by BES at BEPC, the events for J/psi --> p (p) over bar pi(0) and p (p) over bar eta have been selected and reconstructed. Clear peaks are observed around 1480 MeV in p eta(0)((p) over bar pi(0)) invariant mass spectrum and near the threshold for eta production in p eta((p) over bar eta) invariant mass spectrum. A partial wave analysis of J/psi --> p (p) over bar eta data has been performed. Two J(P) = 1/2(-) resonances are observed with mass and width (M, Gamma) at (1540(-17)(+15), 178(-22)(+20)) (1648(-16)(+18), 150)MeV, and are considered to be the nucleon resonances S-11(1535) and S-11(1650) respectively.
