摘要	Based on the effective Lagrangian approach, the J/psi -> p (p) over bar phi decay is studied in an isobar resonance model with the assumption that the phi-meson is produced from intermediate nucleon resonances. The contributions from the N(-)(1/2) (1535), N(3/2+) (1900), N(1/2-) (2090) and N(1/2+) (2100) states are considered. In terms of the coupling constants g(phi NN)(2) and g(psi NN)(2) extracted from the reaction cross section of the pi(-) p -> n phi process, and the partial decay widths of the J/psi -> p (p) over bar eta and J/psi -> p (n) over bar pi(-) processes, respectively, the invariant mass spectrum and the Dalitz plot for J/psi -> p (p) over bar phi decay are predicted. It is shown that there are two types of results. In the type I case, a large peak structure around 2.09 GeV implies that a considerable amount of N phi or qqqs (s) over bar component may exist in the narrow-width N(1/2-) (2090) state, but a tiny qqqs (s) over bar component in the broad-width N(1/2+) (2100) state. In the type II case, a small peak around 2.11 GeV may only indicate the existence of a certain amount of p phi or qqqs (s) over bar component in the narrow-width N(1/2+) (2100) state, but no information for the broad-width N(1/2-) (2090) state. Further BESIII data with high statistics would help us to distinguish the strange structures of these N*s.
