α decay and recoil decay tagging studies of 183Tl -: art. no. 064308

High-spin states in the nucleus Tl-183 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 f(7/2), h(9/2), and oblate h(9/2) configurations. In addition, the prolate i(3/2) structure has also been extended. The systematics of the newly identified structures will be discussed. The alpha decay of Tl-183 has also been investigated. Examination of both delayed and prompt gamma rays in coincidence with the prominent 6333-keV alpha 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 Au-179 and Ir-175.
