Removal of Angular Momentum by Evaporating Neutrons and Photons in the (α, 3n) Reaction

Abstract

We report measurements of the relative intensities of ground-state rotational transitions which occur in deformed nuclei following ($\alpha , 3n$) reactions. An analysis of these intensities shows that the emissions (of neutrons and photons) which precede those in the ground-state band remove considerably more angular momentum from the emitting nuclei than one would estimate using a conventional statistical model.
