TL;DR
This paper reports on the measurement of the cross section and neutron form factor for the process $e^+e^- o nar{n}$ at energies up to 2 GeV using the VEPP-2000 collider and SND detector.
Contribution
It provides new experimental data on neutron-antineutron production cross section and form factor in the 1-2 GeV energy range.
Findings
Measured the $e^+e^- o nar{n}$ cross section.
Determined the effective neutron form factor.
Extended the energy range of previous measurements.
Abstract
The process has been studied at the VEPP-2000 collider with the SND detector in the energy range from threshold up to 2 GeV. As a result of the experiment, the cross section and effective neutron form factor have been measured.
