Gamma rays from the interaction of 14-MeV neutrons with lithium

Measurement of the 477.6-keVγ-ray production cross section following inelastic neutron scattering byLi7

“…Theoretical descriptions of inelastic neutron scattering on 6,7 Li have recently been published by Guo et al [51], Ichinkhorloo et al [52], and Matsumoto et al [53]. All these studies employed the CDCC method with the complex Jeukenne-Lejeune-Mahaux (JLM) effective nucleon-nucleon interaction [54].…”

“…All these studies employed the CDCC method with the complex Jeukenne-Lejeune-Mahaux (JLM) effective nucleon-nucleon interaction [54]. In [51], the experimental total neutron and proton scattering cross sections on 6,7 Li were used to determine energy-dependent normalization factors, which were then used to calculate the angular distributions of elastic and inelastic proton or neutron scattering. In all cases, a reasonably good agreement with experimental data was obtained.…”

“…Lithium and beryllium fluorides are also interesting as coolants for molten salt reactor systems, as described in the Technology roadmap for generation IV nuclear energy systems [3]. Additionally, in deuterium-tritium fusion reactors the fuel cycle requires breeding of tritium from 6,7 Li. The interactions between neutrons and lithium affect the tritium breeding ratio, nuclear heating, and radiation damage.…”

“…The interactions between neutrons and lithium affect the tritium breeding ratio, nuclear heating, and radiation damage. Thus good quality nuclear data on neutron-and proton-induced reactions of 6,7 Li are necessary.…”

“…Since then, the 7 Li(n,n γ ) 7 Li * (477.6 keV) cross section has been measured in several experiments, which are summarized in Table I. The early γ -ray measurements by Freeman * markus.e.j.nyman@gmail.com et al, Bostrom et al [5], and Benveniste et al [6] were performed using scintillation detectors and a ring scatterer. More information about the experimental setup by Benveniste et al is provided in Refs.…”
