Employing a 95-cm³ Ge(Li) detector, positioned 20 m from the Oak Ridge Electron Linear Accelerator white neutron source, the cross section for 478-keV gamma-ray production from 0.48- to 5.0-MeV incident neutrons on ⁷Li was determined. The incident neutron flux was measured with a solid-state, recoil-proton detector and polyethylene radiator. These results, which are an unambiguous measurement of neutron inelastic scattering to the 478-keV ⁷Li state, are listed and compared with recent measurements from other workers and the ENDF/B-V evaluation.
