Light charged particle emission induced by fast neutrons (25 to 65 MeV) on 59Co

Abstract

Double-differential cross sections (energy spectra) for the proton, deuteron, triton and α-particle production in fast neutron induced reactions on cobalt are reported for ten incident neutron energies between 25 and 65 MeV. Energy spectra were obtained at nine laboratory angles between 20° and 160° and extrapolated or interpolated to other ten angles covering uniformly the laboratory angular domain of 0° to 180°. The experimental set-up and procedures for data reduction including corrections and normalization are presented and discussed. Based on the measured double-differential cross sections, energy-differential and total cross sections are reported as well. Experimental cross sections are compared with similar available data from neutron- and proton-induced reactions. Theoretical calculations based on semiclassical exciton model and Hauser–Feshbach statistical theory (GNASH code) and intranuclear cascade model for nucleon-induced interactions (INCL3 code) were done and compared to the experimental results.
