Аннотация:A direct measurement of nn-scattering by colliding free neutrons has never been performed. Indirect measurements
continue to provide inconsistent results, leaving the issue of charge symmetry in the nuclear force
unresolved. At present the Russian pulsed reactor YAGUAR is the best neutron source for such a measurement.
A neutron moderator is installed in the central through channel and the scattered neutrons are detected at a distance
of 12 m from the reactor. An instantaneous value of 1.1x1018 /cm2 s was obtained for the thermal neutron
flux density. The experiment will be performed by the DIANNA Collaboration as ISTC project No. 2286.
