The 58Ni(n,p)58Co, 58Ni(n,2n)57Ni, and 58Ni(n,np)57Co Cross Sections at 14·1 MeV

Abstract

The energy spectrum of the protons which are emitted when nickel is bombarded with 14 ·1 MeV neutrons has been studied recently by several workers-Allan (1957), Colli, Facchini, et al. (1958), and Colli, Pignanelli, et al. (1958). The results of these experiments do not allow an accurate estimate of the relative importance of contributions from the (n,p) reaction and the (n,np) reaction. Such information is necessary when any reaction mechanism is postulated to account for the experimental results. In these experiments, therefore, activation techniques have been used to measure these two cross sections separately for the isotope 58Ni at 14·1 MeV; in addition, the 68Ni(n,2n)57Ni cross section has been remeasured.
