英文摘要	Within the effective Lagrangian approach, we study the p (p) over bar -> psi eta [psi (math) psi(3686), J/psi] reaction at the low energy where the contributions from nucleon pole and low-lying nucleon resonances, N(1520), N(1535), and N(1650), are considered. All the model parameters are determined with the help of current experimental data on the decay of psi -> p (p) over bar eta. Within the model parameters, the total and differential cross sections of the p (p) over bar -> psi eta reaction are predicted. We show that the relative phases between different amplitudes of different nucleon resonance will change significantly the angular distributions of the (p) over barp -> psi eta reaction. Therefore, we conclude that these reactions are suitable to study experimentally the properties of the low-lying nucleon resonance and the reaction mechanisms. We hope that these theoretical calculations can be tested by future experiments.
