    Abstract

    Investigation of neutron production by break-up processes in light-nuclei reactions is described. The energy spectra of neutrons emitted by thick deuterium and helium targets at 0° angle irradiated by a beam of 15.8 MeV protons, 14.1 MeV and 17.1 MeV deuterons, respectively, were measured in an open geometry with stilbene and NE 213 scintillators and with a two-dimensional n-γ discrimination technique. Obtained spectral yields were compared with those of p+Be and d+Be reactions at corresponding energies. This comparison shows that the D- and 4He- targets spectra are substantially harder having lower relative contribution of low-energy neutrons. The p+D reaction looks to be the most effective reaction for producing fast neutrons on low energy cyclotrons.
