摘要	In this work, the cross section of the reaction ??p ??? V(J/??; ??(2S))p from the production threshold to medium energy is studied and systematically analyzed within two gluon exchange model. The obtained numerical results are in agreement with experimental data and other theoretical predictions. Under the assumption of the scalar form factor of dipole form, the value of proton mass radius is calculated as 0.55 ?? 0.09 fm and 0.77 ?? 0.12 fm from the fit to the predicted J/?? and ??(2S) differential cross section, respectively. Finally, the average value of proton mass radius is estimated to be (R2m) = 0.67 ?? 0.11 fm. Moreover, one finds that extracting mass radius from the near-threshold differential cross section of heavy quarkoniums is always affected by large ItImin. These obtained results may provide important theoretical reference for the understanding of nucleon structure and future relevant experiments.
