Abstract

The cross sections of 58Ni(p, γ)59Cu and 58Ni(p, p'γ)58Ni have been measured over the bombarding energy range 1.18-4.20 MeV. The measurements were based on observation of the yields of 59Cu and 58Ni deexcitation γ-rays and also on observation of the yield of γ-rays associated with the β+ decay of 59Cu. The agreement between the two methods used for 58Ni(p, γ)59Cu is very good. The cross sections have been compared with the predictions of global statistical-model calculations. The calculations overestimated the 58Ni(p, γ)59Cu cross section by a factor ∼ 2.5 and the 58Ni(p, p'γ)58Ni cross section by a factor ∼ 1.5. The energies and (p, γ0) resonance strengths of sixty-five resonances which fea..
