  • Beschreibung: <jats:p>The inelastic scattering of fast neutrons from <jats:sup>7</jats:sup>Li nuclei was investigated at the nELBE neutron-time-of-flight facility. The photon production cross section of 478 keV <jats:italic>γ</jats:italic>-rays from the first excited state of <jats:sup>7</jats:sup>Li was determined by irradiating a disc of LiF with neutrons of energies ranging from 100 keV to about 10 MeV. The target position was surounded by a setup of 7 LaBr<jats:sub>3</jats:sub> scintillation detectors and 7 high-purity germanium detectors to detect the de-excitation <jats:italic>γ</jats:italic>-rays. A <jats:sup>235</jats:sup>U 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 some previous measurments but are about 15 % below the recent data taken at the GELINA facility.</jats:p>
