Abstract
Following the -decay of an excited state of is formed that is unstable against neutron emission. The energy distribution of these neutrons has been measured with a hydrogen-filled cloud chamber. The results indicate that the -decay of leaves the nucleus in one or more excited states and that, if there is only one excited state, it is at least 0.6 Mev wide.
