Several fast-neutron activation reactions for copper, europium, hafnium, iron, nickel, silver, terbium and titanium that are important to fusion energy have been investigated in three distinct neutron fields generated by accelerators at Argonne National Laboratory ANL and Los Alamos National Laboratory (LANL), U.S.A., and Japan Atomic Energy Research Institute (JAERI), Tokai, Japan. The experimental data acquired from this collaboration, which has been organized by the International Atomic Energy Agency, include both differential cross sections at 10.0 and 14.7 MeV and integral cross sections for the Be(d,n) thick-target spectrum produced by 7-MeV deuterons. {sup 58}Ni(n,p){sup 58g + m}Co and {sup 93}Nb (n,2n){sup 92m}Nb were used as neutron fluence standards, and the {sup 238}U(n,f) cross section was measured at 10.0 MeV to validate the experimental techniques. Measured differential cross sections are compared with corresponding experimental data from the literature and with values obtained from nuclear model calculations and evaluations. Measured integral cross sections are compared with some earlier experimental results from ANL and with calculated values based on available differential cross-section excitation functions and various representations of the Be(d,n) neutron spectrum. Reasonably good agreement is observed in many of these comparisons.
