Comment on the existence of a lower angular momentum cutoff in the fusion of heavy ions

Abstract

Gauvin et al. have suggested that one possible explanation for the high thresholds of the reactions $^{74}\mathrm{Ge}(^{84}\mathrm{Kr}, xn)^{158\ensuremath{-}x}\mathrm{Er}$ is the existence of a lower limit to the angular momentum of the compound system formed in the fusion step. We note that such lower limits have, in fact, previously been observed in the collisions of water droplets. Investigation of such lower limits may provide interesting new information on nuclear properties.NUCLEAR REACTIONS Heavy ion fusion.
