Abstract
Results are presented from measuring the e+e− → n¯n cross section and effective neutron timelike form factor. Data are collected in 2020–2021 at the VEPP-2000 e+e− collider in the 1891 to 2007 MeV center-of-mass range of energies. The general purpose nonmagnetic SND detector is used to detect neutron–antineutron events. The time-of-flight approach is used to select n¯n events. The measuredcross section is 0.4–0.6 nbn. The neutron form factor in the investigated range of energies varies from 0.3 to 0.2.
