Ni58(p,p′)Ni58Reaction in the 9.1-to 9.55-MeV Range

Abstract

A detailed study of the ${\mathrm{Ni}}^{58}(p,p^{\prime }){\mathrm{Ni}}^{58}$ reaction has been made in the 9.10- to 9.55-MeV incident-proton energy range. Angular distributions of ten resolved excited states below 4.2 MeV have been measured at 25-keV energy intervals. The energy-averaged angular distributions have been compared with Hauser-Feshbach predictions, and spins are suggested for several levels of ${\mathrm{Ni}}^{58}$. Broad structure observed in the yield from the excitation of the 1.456-MeV state is discussed in terms of recently developed intermediate-resonance models.
