Abstract: Results are presented of the study of the e+e-→n and e+e-→p reactions in the energy range from the nucleons production threshold up to 2 GeV. The measurements have been performed at the VEPP-2000 e+e- collider with the SND and CMD-3 detectors 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.
Key words: proton, neutron, electromagnetic form factor, e+e- annihilation, SND, CMD-3
