Abstract

Cross sections were measured for the formation of long-lived 63Ni (T1/2 = 100 a) in (n,p) reaction on 63Cu over the neutron energy range of 7.2 to 14.6 MeV. Radiochemical methods were developed to separate the product 63Ni from the bulk of copper and other radiocontaminants, and to prepare a thin source for soft β counting using a low-level anticoincidence detector. The experimental results are compared with the cross section values obtained via an integration of the emitted proton spectra. For estimating the 63Ni activity, only the activation data are of rel- evance. The present data are also compared with several evaluations, all performed using the statistical model but with different input parameters. The nuclear model calculations predict the excitation functions of (n, charged particle) reactions only with moderate accuracy. For reactions of high importance, accurate radiochemical measurements appear to be mandatory.
