The decay process J/ψ→ p+ X, X → p+ P, where p,p and P are the proton, antiproton and pseudoscalarstates, respectively, has been studied in terms of the angular distribution and the generalized moment analysis methods.The result shows that we can identify the spin, but cannot determine the parity of the baryon resonance state X producedin the process J/ψ→ p + X, X → p + P.
