Abstract
Using mass-separated sources, the -decay properties of and were investigated. Limits of decay to the first and levels in suggest a spin for the odd-odd parent; also delayed proton emission and an indication of delayed -particle emission were observed to follow decay. The -decay branch of the -emitting nucleus was identified for the first time by the observation of one intense 133.2-keV ray. This transition deexcites a 133.2-keV level in which is fed by an allowed transition with a value of 3.6 ± 0.3.
