The proposed high flux lithium antineutrino source is based on 7Li(n,g)8Li-activation and subsequent fast beta-decay (0.84 s) of the 8Li isotope with emission of hard antineutrinos with energy up to 13 MeV. In the discussed scheme the…

An intensive antineutrino source with a hard spectrum (with energy up to 13 MeV, average energy 6.5 MeV) can be realized on the base of beta-decay of short living isotope 8Li (0.84 s). The 8Li isotope (generated in activation of 7Li…
