Abstract: Excitation function of the reaction Ni60(p,γ)Cu61 was measured via the activation technique in the energy range of 1.3-16.0 MeV using a low-energy accelerator and a small cyclotron. The results are comparable to those previously obtained via prompt γ counting. In addition excitation functions of the more common competing Ni60(p,n)Cu60 and Ni60(p,α)Co57 reactions were also measured. Theoretical calculations on proton-induced reactions on Ni60 were performed using the nuclear model code talys. The results suggest that near the threshold of the reaction the compound nucleus mechanism dominates. Thereafter the contribution of direct interactions becomes rather strong, especially between 4 and 6 MeV, i.e., just below the threshold of the Ni60(p,n)Cu60 reaction. The cross section at the maximum of the excitation function of each of the three reactions, namely, Ni60(p,γ)Cu61,Ni60(p,n)Cu60, and Ni60(p,α)Co57, amounts to 2, 320, and 85 mb, respectively. The (p,n) reaction is thus the most commonly occurring process, and the (p,γ) reaction is the weakest, possibly due to higher probability of particle emission than γ-ray emission from the highly excited intermediate nucleus Cu61 formed in the interaction of a proton with the target nucleus Ni60.
