摘要利用正负电子对撞机VEPP-2000上SND和CMD-3探测器从2011至2012年获取的对撞数据,给出了从产生阈值到2GeV能区e^+e^-nn和e^+e^-→pp的实验结果.同时,讨论了核子的电磁形状因子,并对结果的改进进行了展望. Results are presented of the study of the e^+e^-→nn and e^+e^-→pp reactions in the energy range from the nucleons production threshold up to 2GeV.The measurements have been performed at the VEPP-2000 e^+e^-collider with the SND and CMD-3detectors using the events collected during the data taking runs of 2011 and 2012.Also discussed here are the obtained electromagnetic form factors of nucleons and future plans of these results improvement.
