An Interpretation of Proton Spectra from the 58ni(n,p)58co Reaction at Neutron Energy Close to 20 Mev

摘要

The differential cross.sections of the 58Ni(n,p)58Co reaction have been measured at 17.3 MeV neutron energy. The comparison of the results with data obtained earlier at 18.5 MeV suggests that multistep proton emission with excitation of the GDR as a doorway state takes place at these neutron energies.
