Searches have been made for short-lived isomers in /sup 180/Lu suggested by the preceding paper. Samples of /sup 180/Lu were produced via the /sup 180/Hf(n,p) reaction. Evidence for decay of a /sup 180/Lu isomer was sought by examining the decay curves of the known /sup 180/Lu and /sup 180/Hf/sup m/ delayed ..gamma.. rays, and by searching for previously unidentified delayed ..gamma.. rays. No evidence for a /sup 180/Lu isomer was observed for half-lives between 10 and 300 sec. The relevance of these observations for understanding the nucleosynthesis of /sup 180/Ta/sup m/ is discussed.
