dc.description.abstractThe neutron inelastic scattering cross section of 23Na has been measured in response to the relevant request of the OECD-NEA High Priority Request List, which requires a target uncertainty of 4% in the energy range up to 1.35 MeV for the development of sodium fast-cooled reactors. The measurement was performed at the GELINA facility with the Gamma Array for Inelastic Neutron Scattering (GAINS), featuring eight high purity germanium detectors. The setup is installed at a 200 m flight path from the neutron source and provides high resolution measurements using the (n, n'g)- technique. The sample was an 80 mm diameter metallic sodium disk prepared at IRMM. Transitions up to the seventh excited state were observed and the differential gamma cross sections at 110º and 150º were measured, showing mostly isotropic gamma emission. From these the gamma production, level and inelastic cross sections were determined for neutrons energies up to 3837.5 keV. The results agree well with existing data and the evaluated nuclear data libraries in the low energies, and provide new experimental points in the little studied region above 2 MeV. Following a detailed review of the methodology used for the gamma efficiency calibrations and flux normalization of GAINS data, an estimated total uncertainty of 2.2 % was achieved for the inelastic cross section integrals over the energy ranges 0.498 -1.35 MeV and 1.35 - 2.23 MeV, meeting the required targets.en_GB
