Abstract

The cross section was measured at center of mass (c.m.) energies from the threshold to 1908 MeV. The experiment to measure the cross section has been carried out at the VEPP-2000 collider in 13 energy points. The SND detector is used to detect the produced neutron–antineutrons () events. A special time measurement system on the calorimeter was used to select the time-delayed events. The measured cross section is 0.4–0.6 nb. The neutron effective timelike form factor in the energy range under study varies from 0.3 to 0.6. [ABSTRACT FROM AUTHOR]
