Abstract

The β ⁺/EC decay of ^182,184Tl to excited states in the daughter nuclei ^182,184Hg has been investigated at the CERN on-line isotope mass separator facility. In both Tl nuclei two β-decaying states were observed. In the case of ¹⁸⁴Tl, narrow-band laser spectroscopy could be used to disentangle the decay of both isomers. In ¹⁸²Hg a precise energy of 335 (1) keV for the 0+ 2 state was measured together with its feeding from a tentatively proposed 2+ 3 state at 973 keV. Large conversion coefficients for the 2 ⁺ + 2 ₁ → 2 transition in ^182,184Hg were measured to be 7.2 (13) and 14.2 (36), respectively, evidencing a strong E0 component.
