摘要	Using a sample of 58 million J/psi events collected with the BESII detector at the BEPC, more than 100 000 J/psi -> p (p) over bar pi(0) events are selected, and a detailed partial wave analysis is performed. The branching fraction is determined to be Br(J/psi -> p (p) over bar pi(0)) = (1.33 +/- 0.02 +/- 0.11) x 10(-3). A long-sought missing N, first observed in J/psi -> p (n) over bar pi(-), is observed in this decay too, with mass and width of 2040(-4)(+3) +/- 25 MeV/c(2) and 230(-8)(+8) +/- 52 MeV/c(2), respectively. Its spin-parity favors 3+/2. The masses, widths, and spin parities of other N states are obtained as well.
