Abstract：
Based on 58 million J/ψ data collected with the BESⅡ detector at the BEPC, Partial Wave Analysis(PWA) is performed on J/ψ→ppπ⁰. The new excited baryon N(2065) is confirmed. Clear signals for other N* states are observed and the corresponding masses, widths and spin-parity are also measured. Processes such as J/ψ→ppη, ppη′ are also studied and the branching ratios are measured.
