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