Description

Using mass-separated sources, the β-decay properties of /sup 154/Lu and /sup 154/Yb were investigated. Limits of /sup 154/Lu decay to the first 8+ and 6+ levels in /sup 154/Yb suggest a 7+ spin for the odd-odd parent; also delayed proton emission and an indication of delayed α-particle emission were observed to follow /sup 154/Lu β decay. The β-decay branch of the α-emitting nucleus /sup 154/Yb was identified for the first time by the observation of one intense 133.2-keV γ ray. This transition deexcites a 1+ 133.2-keV level in /sup 154/Tm which is fed by an allowed 0+→1+β transition with a logft value of 3.6 +- 0.3
