Evidence for Nonstatistical Effects in the ReactionDy163(n,γ)Dy164

Abstract

$\gamma$-ray intensities from 17 resonances with $J=3\mathrm{} \mathrm{to} 22$ final states in ${\mathrm{Dy}}^{164}$ reveal that there are significant correlations between partial radiative widths and reduced neutron widths. The two-particle, one-hole doorway-state concept and channel-capture mechanisms may be invoked to explain these correlations.
