|Abstract:||Neutron activation cross sections for the 63Cu(n, )60Co, 59Co(n,p)59Fe, and 58Ni(n,t)56Co reactions were measured in the energy range from 13 to 21 MeV. The irradiations were carried out at the 7-MV Van de Graaff accelerator at IRMM, Geel. Quasi-monoenergetic neutrons were produced via the 3H(d,n)4He reaction at 1-, 2-, 3-, and 4-MeV incident deuteron energy. All reaction cross sections measured in the present work are referenced to the 27Al(n, )24Na standard reaction cross section. Neutron flux spectra were determined by an activation spectral index method in combination with TOF spectrum measurements. Standard -ray spectrometry was employed for the measurement of radioactivity. The measured results are compared with work by other authors, TALYS-0.57 and EMPIRE-II model calculations, and current evaluated data files. The new results contribute substantially to the experimental database of the measured reactions. Recommendations are provided for the best evaluations for the 59Co(n,p)59Fe, and 63Cu(n, )60Co reactions. For the 58Ni(n,t)56Co reaction no current evaluation is in good agreement with all available data. For this reaction further measurements would help to guide new modeling efforts.|
