Excitation function measurements are reported for reactions induced in natural nickel with 9–86 Mev α-particles. Cumulative cross sections were obtained for the production of60(m+g)Co,58(m+g)Co,57Co and56Co. The stacked-foil method was used to measure product yields by gamma-spectrometry with a Ge intrinsic detector. The experimental data (supplemented with previously reported cross sections by other authors were compared with the calculated values obtained by means of the hybrid model.
