The Possibility of Obtaining a Quasi-Monoenergetic Beam of Neutrons on a Photoneutron Source

摘要

A kinematic simulation of the γ +_(9)Be →_(8)Be + n reaction is performed, in which the beam of quasi-monoenergetic photons is considered the input beam. The possibility of obtaining a beam of quasimonoenergetic neutrons at the photoneutron source of the Russian Academy of Sciences’ Institute for Nuclear Research is demonstrated. The efficiency of obtaining quasi-monoenergetic neutrons and the effect the quasi-monochromatization parameters of the photon bremsstrahlung spectra have on the neutron energy distribution are investigated.
