Measuring of a few integral data in the ΣΣ neutron field

Measurements of absolute reaction rates for the nonfissionable isotopes were obtained at the Institute for Nuclear Technology (ITN) Romania, using activation detector foils exposed at the centre of ΣΣ. The average microscopic integral cross sections sigma were obtained for the following reactions: 197Au(n,γ), 115In(n,γ), 115In(n,n'), 27Al(n,α), 46Ti(n,p), 47Ti(n,p), 48Ti(n,p) and 58Ni(n,p). The same data, the absolute reaction rates and the average microscopic integral cross sections, for the principal fissionable isotopes were performed in the ΣΣ-ITN facility by means of absolute fission chambers. These average fission cross sections for 235U, 239Pu, 238U, 237Np, 232Th, 233U, 241Pu were determined. (author)
