/ Tang, T.L. (Argonne) ; Kay, B.P. (Argonne) ; Hoffman, C.R. (Argonne) ; Schiffer, J.P. (Argonne) ; Sharp, D.K. (Manchester U.) ; Gaffney, L.P. (CERN) ; Freeman, S.J. (Manchester U.) ; Mumpower, M.R. ; Arokiaraj, A. ; Baader, E.F. (CERN) et al.
The nuclei below lead but with more than 126 neutrons are crucial to an understanding of the astrophysical $r$-process in producing nuclei heavier than $A\sim190$. Despite their importance, the structure and properties of these nuclei remain experimentally untested as they are difficult to produce in nuclear reactions with stable beams. [...]

Background: Shape coexistence in heavy nuclei poses a strong challenge to state-of-the-art nuclear models, where several competing shape minima are found close to the ground state. A classic region for investigating this phenomenon is in the region around $Z=82$ and the neutron mid-shell at $N=104$. [...]

First β-decay spectroscopy of $^{135}$In and new $β$-decay branches of $^{134}$In
/ IDS Collaboration
The $\beta$ decay of the neutron-rich $^{134}$In and $^{135}$In was investigated experimentally in order to provide new insights into the nuclear structure of the tin isotopes with magic proton number $Z=50$ above the $N=82$ shell. The $\beta$-delayed $\gamma$-ray spectroscopy measurement was performed at the ISOLDE facility at CERN, where indium isotopes were selectively laser-ionized and on-line mass separated. [...]

Quadrupole Moments of $^{29}$Mg and $^{33}$Mg

The quadrupole moments of 29Mg and 33Mg have been constrained by collinear laser spectroscopy at CERN-ISOLDE. The values are consistent with shell-model predictions, thus supporting the current understanding of light nuclei associated with the "island of inversion"..

Decay studies of the long-lived states in $^{186}$Tl
/ IDS Collaboration
Decay spectroscopy of the long-lived states in $^{186}$Tl has been performed at the ISOLDE Decay Station at ISOLDE, CERN. The $\alpha$ decay from the low-spin ($2^−$) state in $^{186}$Tl was observed for the first time and a half-life of 3.4$^{+0.5}_{−0.4}$ s was determined. [...]
