Resumo

Obtaining intense neutron fluxes are required for production of radioactive isotopes, radiation testing of promising materials, neutron diffraction, neutron capture therapy and other applications. The interaction of deuterons with lithium is characterized by a high neutron yield, a wide variety of reactions, but the available experimental data on the reaction cross-section are scarce and contradictory, which does not allow reliable estimation of the yield and spectrum of generated neutrons. In this work, effective partial cross-sections of the nuclear reactions 7Li(𝑑, 𝑛)8Be with the formation of the Be nucleus in the ground and first excited states at deuteron energies from 0.4 to 2.1 MeV were measured at accelerator based neutron source VITA using developed RBN-A1 fast neutron spectrometric radiometer. It is shown that measurements by the fast detector radiometer with two diamond spectrometric detectors provide a number of advantages over the traditionally used measuring path scintillation detector. Analysis of the high-energy part of the amplitude spectra of diamond detectors, determined by the reactions 12C(𝑛, α)9Be and 12C(𝑛, α)9Be*, made it possible to measure the effective partial cross sections of the nuclear reaction 7Li(𝑑, 𝑛)8Be with the formation of the Be nucleus in the ground and especially in the first excited state.
