|Abstract:||The inelastic scattering of fast neutrons from 7Li nuclei was investigated at the nELBE neutron time-of-flight facility. The photon production cross section of 478 keV gamma-rays from the first excited state of 7Li was determined by irradiating a disc of LiF with neutrons of energies ranging from 100 keV to about 10 MeV. The target position was surrounded by a setup of 7 LaBr3 scintillation detectors and 7 high-purity germanium detectors to detect the de-excitation gamma-rays. A 235U fission chamber was used to determine the incoming neutron flux. The number of detected photons was corrected for the detection efficiency, multiple scattering and the time-of-flight dependent data acquisition dead time. The preliminary results show reasonable agreement with previous measurements but clearly deviate from recent data taken at the GELINA facility.|
