Ni 58 ( α , α ′ ) Ni 58 and the Nature of High-Lying States in Ni 58

We have studied levels in $^{58}\mathrm{Ni}$ up to 10 MeV excitation energy through the ($\ensuremath{\alpha},{\ensuremath{\alpha}}^{\ensuremath{'}}$) reaction at 30 MeV and found surprising overall agreement between the observed spectra and those from $\ensuremath{\alpha}$-transfer reactions.
