Sputtering of Nb and Au by (d, t) Neutrons

Abstract
Neutron-sputtering ratios are reported for (d, t) neutrons incident upon Nb and Au foils. The measured ratios are lower than most previous results. For annealed Au as well as for cold-worked Nb the best values for the sputtering ratios are in the range Sn(1.22.5)×105. These results are in good agreement with theoretical predictions. A careful search for neutron-induced micron-sized particles yielded negative results.
