## Abstract

Integral activation cross section ratios of Ni58 (n,x)Co57, Ni60(n,p)Co60, Cu63(n,{alpha})Co60 and Au197(n,3n)Au195 have been measured relative to Al27(n,{alpha})Na24, in the neutron spectrum produced by 23.2 MeV deuterons incident on a thick Be target. Validation of these cross sections in a high energy neutron spectrum is the object of this work. A close examination of the spectrum of our facility (ITER1) and sensitivity functions shows that the response of these cross sections is quite significant between 10-15 MeV to 15-22 MeV. Several evaluated cross sections libraries have been used to calculate the integral activation cross sections in the irradiation spectrum. In general the agreement between ENDF/B-VI or IRDF90 calculated values and experimental results is excellent for Ni58(n,x)Co57, Cu63(n,{alpha})Co60 and Au197(n,3n)Au195, well within the experimental errors. However for Ni60(n,p)Co60, excluding evaluated libraries based on too high Paulsen data (Chinese, JENDL), the nuclear model calculation evaluated library EFF-2 shows a better agreement (E/C-1 {approx} 9.7%) with our experimental result than ENDF/B-VI (E/C-1 {approx} 16%). (author). 18 refs, 6 figs, 6 tabs.
