Abstract

High-resolution fast-neutron spectra (to about 1%) have been obtained by means of the proton-radiator method, detecting the proton recoils with solid-state detector telescopes and particle identifier circuits. Our spectra confirm a broad peak at 1.4 MeV and resolve another at 3.2-MeV excitation.
