Excitation functions were measured by the stacked-foil technique for Ni61(p,)58Com and Ni61(p,)58Com+g reactions using 88.84% enriched Ni61 from threshold up to 18.6 MeV. Thin samples of Ni61 were prepared by electrodeposition on gold foils. The radioactivity of the activation products was determined via high resolution x- and -ray spectrometry. From the measured experimental data isomeric cross-section ratios [m/m+g] were deduced. Statistical model calculations taking into account precompound effects were performed for the strong Ni61(p,xn) channels as well as for the weak Ni61(p,) process. The experimental Ni61(p,xn) and Ni61(p,) excitation functions are described well by the calculation over the whole investigated energy range. The isomeric cross-section ratio for the isomeric pair Com,58g formed in the Ni61(p,) process is also reproduced well by the model calculation, provided the input level scheme and the spin distribution are properly taken into account.
