Measurement of $gamma$-ray production via neutron-$^{16}$O reaction using a 77 MeV quasi-monoenergetic neutron beam


Abstract in English

Understanding of $gamma$-ray production via neutron interactions on oxygen is essential for the study of neutrino neutral-current quasielastic interactions in water Cherenkov detectors. A measurement of $gamma$-ray production from such reactions was performed using a 77~MeV quasi-monoenergetic neutron beam. Several $gamma$-ray peaks, which are expected to come from neutron-${rm ^{16}O}$ reactions, are observed and production cross sections are measured for nine $gamma$-ray components of energies between 2 and 8~MeV. These are the first measurements at this neutron energy using a nearly monoenergitic beam.
