Light charged particle emission induced by fast neutrons with energies between 25 and 65 MeV on iron

Abstract

Double-differential cross sections (energy spectra) for proton, deuteron, triton and alpha-particle emission in fast neutron-induced reactions on iron 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 ten other angles extending the angular distribution from 2.5° to 177.5°. The experimental set-up and the procedure for data taking and data reduction are briefly presented. Deduced energy-differential and total cross sections are also reported. Experimental cross sections are compared with data from proton-induced reactions on 54Fe and 56Fe, and with our data from neutron-induced reactions on cobalt. Theoretical calculations of GNASH and TALYS reaction codes are also compared to the experimental data.
