The structure of the odd-odd, neutron-rich bismuth isotopes provides an excellent testing ground for shell-model calculations. While the low-lying structure in $^{210}$Bi ($Z = 83$, $N = 127$) is expected to be dominated by $(\pi h_{9/2})(\nu g_{9/2})$ configurations, the gradual filling of the $\nu g_{9/2}$ and higher-lying shells will alter this situation. For $^{210,212,214}$Bi, $I^\pi =...

The neutron-deficient mercury isotopes ($Z=80$) around $N=104$ represent one of the most prominent examples of shape coexistence [1]. This region has been extensively studied using various experimental techniques, such as laser spectroscopy [2,3], decay spectroscopy studies [4-6] and Coulomb excitation [7,8]. These studies point to the coexistence of two classes of states with strong mixing...

One possible extention of the standard model of particle physics is the addition of left-handed scalar and tensor currents to the well-established V-A model of the weak interaction. These contributions can be tested by nuclear beta decay. The 0+ - 0+ decay of 10C and other light even-even nuclei can in particular determine limits on scalar currents.

The two prevailing models for nuclear structure are the shell model and the collective model, which characterise predominantly separate regions of the nuclide chart. Nuclei at the edges of, and/or between these regions are essential for broadening our understanding of both the models themselves and nuclear structure more generally. The proton-pair, neutron-hole-pair nucleus of $^{208}$Po...

The $\beta$ decay of $^{208}$Hg into the one-proton hole, one neutron-particle $_{ 81}^{208}$Tl$_{127}$ nucleus was investigated at the ISOLDE Decay Station. Shell-model calculations describe well the level scheme deduced, validating the proton-neutron interactions used, with implications for the whole of the N$>$126, Z$<$82 quadrant of neutron-rich nuclei. While both negative and positive...
