Microscopic description of cluster emission with the Gogny force

摘要

Cluster radioactivity is microscopically described using the mean field approach with the effective phenomenological Gogny interaction. As driving coordinate the axially symmetric octupole moment is used. Owing to the microscopic approach used, it is possible to compute collective masses consistently and therefore it is also possible to compute spontaneous emission half lives. The present approach has been applied to the cluster radioactivity emission in Ra-226 and the results for the half lives and other quantities agree well with experiment.
