“…This expectation was recently confirmed experimentally by our detailed β-decay study of 180 Tl (N = 99) [18], in which the spin of I = (4, 5) was proposed for the ground state of this isotope. Most probably, the shape of this state is spherical owing to the sphericity of the underlying proton configuration.…”

“…First of all, no direct production of 178 Hg was possible in our experiments, as mercury isotopes cannot be ionized either by surface ionization or by laser ionization tuned to the thallium excitation scheme. This was proved in the measurements with 180 Tl, when the ratio between 180 Tl and 180 Hg was compared with the laser tuned on thallium ionization and with the laser tuned off [18]. Therefore, all α decays of 178 Hg observed in Fig.…”

“…A detailed description of the setup and analysis techniques are given in our papers [6,7,18], which report the analysis of 180 Tl data from Run I. In both experiments, the 178 Tl nuclei were produced by the 1.5-μA, 1.4-GeV proton-induced spallation reactions of a thick 50 g/cm 2 UC x target of ISOLDE mass separator at CERN.…”

The first identification of the β-delayed fission of this isotope was made and its probability P βDF ( 178 Tl) = 0.15(6)% was determined. An asymmetric fission fragment mass distribution of the daughter isotope 178 Hg (populated by the β decay of 178 Tl) was deduced based on the measured fission fragment energies. The fine-structure α-decay pattern of 178 Tl allowed the low-energy states in the daughter nucleus 174 Au to be studied.

“…One striking example of shape coexistence occurs in 186 Pb, where the ground state is spherical, while the first two excited states are believed to be oblate and prolate [4,5]. In the 80 Hg isotopes a similar effect is observed, with the coexisting shapes approaching the ground state at N = 102 [6,7]. The variety of nuclear configurations in this region impacts the nuclear shape as indicated by the changes in the charge radii: the large odd-even staggering in the 80 Hg isotopes around N = 102 [8] and the progressive departure from sphericity in the 84 Po isotopes for N 116 [9,10].…”

High-resolution laser spectroscopy was performed on 206 Fr with the collinear resonance ionization spectroscopy (CRIS) experiment at CERN-ISOLDE. The hyperfine structure and isotope shift of the ground, first isomeric and second isomeric states were measured. The hyperfine components were unambiguously assigned to each nuclear state by means of laser-assisted nuclear decay spectroscopy. The branching ratios in the α decay of 206 Fr and 202 At were also measured for the first time with isomerically purified beams. The extracted hindrance factors allow determination of the spin of the ground, first isomeric, and second isomeric states in 202 At and 198 Bi.
