Abstract

The activation cross sections of 14.7 MeV neutron-induced reactions have been measured in Se isotopes. The experimental results have been compared with the predictions of the statistical theory of the compound nucleus. For some reactions it has been possible to determine the isomeric ratios; these ratios have been analysed using the statistical calculation of Huizenga and Vandenbosch, and estimates have been obtained for the parameter σ which characterizes the spin dependence of the nuclear level density.

    Neutron capture on selenium has also been evaluated for the indirect production on 77As. Minetti et al. measured the activation reactions of 80Se(n,α)77Ge and 80Se(n,α)77mGe with 14.7 MeV neutrons [81]. The cross-section was determined by the activation method where the resulting beta and gamma emissions are recorded.

    The 275.93 keV gamma-ray emitted in the 81gSe decay was used to deduce the value of the 82Se(n,2n)81gSe reaction cross section. As shown in Table 2, in the 14.4–15 MeV energy range, the data show considerable scatter, and our value is somewhat higher than those of [1,4,5,63]. It must be pointed that the cross sections for 82Se(n,2n)81gSe reaction at neutron energy 13.5 and 14.1 MeV are first reported here.
