Abstract

A broad enhancement above the continuum observed in 58, 60, 62, 64Ni(n, p) at 59.6 MeV is interpreted as the parent analog of the T> component of the giant dipole resonance. A continuum parameterization is used to extract the resonance cross section. The angular distributions for the state are most consistent with the Steinwedel-Jensen model for the giant dipole. The sum-rule strength is somewhat greater than observed with photonuclear measurements. A measurement of the blocking of the cross section with neutron excess is made, and is consistent with theoretical predictions.
