ENERGY SPECTRA OF NEUTRONS PRODUCED BY ALPHA PARTICLES IN THICK TARGETS OF LIGHT ELEMENTS
Energy spectra of neutrons produced by 4-5.5 MeV alpha- particles in thick targets of C, Mg, Al, Si, BN, CaF-2, Al-2O-3, SiO-2 and UO-2 have been determined. A Van de Graaff accelerator has been used as a pulsed alpha-particle source and neutrons were detected at 0,30,60,100 and 140beta by a calibrated NE213 scintillator used as a time-of-flight spectrometer. Angle-integrated spectra were derived not only for the above materials but also for B,F and O. Energy integration delivers yields in good agreement with recent results from 4pi moderator detector measurements.
