Shape coexistence in neutron-deficient Hg188 investigated via lifetime measurements

“…The experimental values marked with (a) and the branching ratios (Br) are taken from Ref. [42]. not large and K is likely to be approximately a good quantum number.…”

Competition of rotation around the intermediate and long axes in Tl193

“…For instance the yrast π h 11/2 ⊗ νi −1 13/2 configuration in the odd-odd 188,190,192,194 Au nuclei produces the I π = 11 − isomeric state, instead of the fully aligned I π = 12 − state. Moreover the π h 11/2 ⊗ νi −2 13/2 configuration produces the partially aligned I π = 31/2 − isomer in 189,191 Au while the fully aligned state would have I π = 35/2 − (evaluated experimental data on these Au isotopes can be found in [79][80][81][82][83][84]).…”

Shape coexistence in the neutron-deficient lead region: A systematic study of lifetimes in the even-even $^{188-200}$Hg with GRIFFIN

“…This cycling configuration was designed to maximize the activity of 188m Tl while suppressing the other decay products present. In order to remeasure the 188 Tl and 188m Tl half-lives (T 1/2 (2 − )=71(1) s and T 1/2 (7 + )=71(2) s, respectively [20]), a small fraction of the data was taken with a different tape cycle; 1.5 s of tape movement, 30 s background measurement, 210 s beam-on and 350 s of decay time with the beam off. The detailed analysis of the decays from these two levels is being prepared for publication [21].…”
