AbstractAbstract
[en] Time-of-flight techniques and a 95-cm3 Ge(Li) detector positioned 20 m from the ORELA white neutron source have been utilized to measure 1250 cross sections for the production of gamma rays in 238U and 7Li samples by 0.48 to 5.0-MeV neutrons. The incident neutron flux was determined with a proton-recoil telescope which used a solid-state, recoil-proton detector. Altogether, 28 cross sections for 238U transitions from levels with 680 to 1224 keV of excitation were measured. In addition, 7 branching ratios for weak 238U transitions and the 7Li(n,n'γ)7Li* (478 keV) cross section were measured. From these data and other level-decay information, preliminary neutron inelastic scattering cross sections were constructed and compared with those at 680, 732, 827, 965, 1048, and 1170-keV of excitation from the proposed ENDF/B-V evaluation. 40 references
