Abstract

High-spin states in the nucleus Tl183 have been studied using the recoil decay tagging and recoil tagging techniques. The data have enabled new structures to be identified which are believed to be based on prolate f72, h92, and oblate h92 configurations. In addition, the prolate i32 structure has also been extended. The systematics of the newly identified structures will be discussed. The α decay of Tl183 has also been investigated. Examination of both delayed and prompt γ rays in coincidence with the prominent 6333keV α decay, together with an investigation of the effects of the summing of L electrons, allow assignment of transitions and the construction of tentative low-spin decay schemes for Au179 and Ir175.
