The energy dependence of neutron damage in Cu and Nb

Primary recoil spectra and specific damage energies have been computed for neutron interactions in Cu and Nb at neutron energies up to 32 MeV. The calculations are based on theoretical neutron cross sections and are in good agreement with recent radiation damage experiments using high energy neutrons from the Be(d,n) reaction. The results are particularly relevant to the understanding of radiation effects from high energy deuteron-breakup neutron sources. (Auth.)
