Abstract

Nuclear data underpin a number of applications across nuclear reactor design, medicine, astrophysics, nonproliferation, national security, and other related fields. However, data are conflicting or missing across the spectrum of isotopes and reactions, and theoretical calculations can only go so far to predict nuclear properties. A key reaction with incomplete data is neutron inelastic scatter on 16O, which reduces neutron energies and produces high-energy gamma rays that are often not taken into account in simulations of nuclear reactors, nuclear weapon detonations, nuclear fusion, and other areas. To fill these gaps, the Gamma-Energy Neutron-Energy Spectrometer for Inelastic Scattering, or GENESIS, was designed and built at the Lawrence Berkeley National Laboratory’s 88-inch Cyclotron facility to conduct cross section measurements for neutron inelastic scatter reactions on a variety of isotopes utilizing neutron-gamma coincidence measurements. An experiment was conducted to determine the energy- and angle-differential cross sections for several excited states in 16O for incident neutron energies of 1-23 MeV.
