Some effects of high temperature and density on the half-lives of /sup 180/Ta/sup g/ and /sup 180/Ta/sup m/ have been investigated. It is found that the half-life of /sup 180/Ta/sup g/ is greater in stellar environments than in the laboratory, while that of /sup 180/Ta/sup m/ may be much shorter than its laboratory value. The implications of these results for the nucleosynthesis of /sup 180/Ta are discussed.
