High-spin states in the nucleus 183Tl 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 f7∕2 , h9∕2 , and oblate h9∕2 configurations. In addition, the prolate i3∕2 structure has also been extended. The systematics of the newly identified structures will be discussed. The α decay of 183Tl has also been investigated. Examination of both delayed and prompt γ rays in coincidence with the prominent 6333-keV 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 179Au and 175Ir .
