Abstract

alpha-decay spectroscopy of 182,184Tl has been performed at the CERN Isotope Separator On-Line (ISOLDE) facility. New fine structure alpha-decays have been observed for both isotopes. alpha-branching ratios of 0.089(19)%, 0.047(6)% and 1.22(17)% have been deduced for the (10-), (7+) and (2+) states respectively in 184Tl and a lower limit of 0.63(7)% for the alpha-branching ratio of 182Tl. A half-life of 9.5(2) s has been extracted for the (2+) state in 184Tl. For 182Tl a half-life of 1.9(1) s has been deduced. Using alpha-gamma coincidence analysis, multiple gamma-rays were observed de-exciting levels in 178;180Au fed by 182;184Tl decays. However, due to the complex fine-structure decays and limited knowledge about the structure of the daughter nuclei, only partial alpha-decay schemes could be constructed for both isotopes. Reduced widths have been calculated and are compared with values obtained in neighboring odd and even thallium isotopes.
