摘要：

Nuclear reactions of Nb-93, Ta-181 and Au-197 induced by secondary neutrons produced by irradiation of a thick, stainless steel target with 40 MeV/nucleon Ar-40 ions were investigated by off-line gamma-ray spectroscopy. Yields of the radioactive products have been determined relative to that of Na-24 produced by the Al-27(n,alpha)Na-24 reaction. The slopes of the mass distributions deduced from the experimental data are independent of the target species. Up to 7 nucleons were removed from the target nuclei, indicating significant presence of the neutrons with energies higher than 70 MeV.
