Detailed structure of Sn131 populated in the β decay of isomerically purified In131 states / IDS Collaboration
The excited structure of the single-hole nucleus Sn131 populated by the β− decay of In131 was investigated in detail at the ISOLDE facility at CERN. This new experiment took advantage of isomeric purification capabilities provided by resonant ionization, making it possible to independently study the decay of each isomer for the first time. [...]

β decay of the ground state and of a low-lying isomer in Bi216 / IDS Collaboration
A detailed β-decay study of the low- and high-spin states in Bi216 has been performed at the ISOLDE Decay Station at the CERN-ISOLDE facility. In total, 48 new levels and 83 new transitions in the β-decay daughter Po216 were identified. [...]

Half-life determination of $^{215}$At and $^{221}$Ra with high-purity radioactive ion beams / Bara, S (KU Leuven, Dept. Phys. Astron.) ; Jajčišinová, E (KU Leuven, Dept. Phys.

At CERN-ISOLDE, high-purity radioactive ion beams of $^{219}$Fr and $^{221}$RaF were investigated with $\alpha$-decay spectroscopy at the CRIS and ASET experiments in the course of three different experimental campaigns. The half-life of $^{215}$At, $\alpha$-decay daughter of $^{219}$Fr, is measured to be 36.3(3)[9]μs, and that of $^{221}$Ra was determined to be 26.2(1)[6]s, both of which are well in line with the trends in this region of the nuclear landscape but at odds with some of the reported literature..

High-Precision Mass Measurements of Neutron Deficient Silver Isotopes Probe the Robustness of the <math display="inline"><mrow><mi>N</mi><mo>=</mo><mn>50</mn></mrow></math> Shell Closure / Ge, Zhuang (Jyvaskyla U.) ; Reponen, Mikael (Jyvaskyla U.) ; Eronen, Tommi (Jyvaskyla U.) ; Hu, Baishan (TRIUMF ; ORNL, Oak Ridge (main) ; Oak Ridge) ; Kortelainen, Markus (Jyvaskyla U.) ; Kankainen, Anu (Jyvaskyla U.) ; Moore, Iain (Jyvaskyla U.) ; Nesterenko, Dmitrii (Jyvaskyla U.) ; Yuan, Cenxi (SYSU, Guangzhou) ; Beliuskina, Olga (Jyvaskyla U.) et al.
High-precision mass measurements of exotic $^{95-97}$Ag isotopes close to the $N = Z$ line have been conducted with the JYFLTRAP double Penning trap mass spectrometer, with the silver ions produced using the recently commissioned inductively-heated hot cavity catcher laser ion source at the Ion Guide Isotope Separator On-Line facility. The atomic mass of $^{95}$Ag was directly determined for the first time. [...]

Isomers close to doubly-magic $^{78}_{28}$Ni$_{50}$ provide essential information on the shell evolution and shape coexistence near the ${Z=28}$ and ${N=50}$ double shell closure. We report the excitation energy measurement of the $1/2^{+}$ isomer in $^{79}_{30}$Zn$_{49}$ through independent high-precision mass measurements with the JYFLTRAP double Penning trap and with the ISOLTRAP Multi-Reflection Time-of-Flight Mass Spectrometer.

Nuclear charge radius of $^{26m}$Al and its implication for V$_{ud}$ in the quark-mixing matrix / Plattner, P. (CERN ; Innsbruck U. ; Heidelberg, Max Planck Inst.) ; Wood, E.

Collinear laser spectroscopy was performed on the isomer of the aluminium isotope $^{26m}$Al. The measured isotope shift to $^{27}$Al in the $3s^{2}3p\;^{2}\!P^\circ_{3/2} \rightarrow 3s^{2}4s\;^{2}\!S_{1/2}$ atomic transition enabled the first experimental determination of the nuclear charge radius of $^{26m}$Al, resulting in $R_c$=\qty{3.130±.015}{\femto\meter}.

Background: The mercury isotopes around $N=104$ are a well-known example of nuclei exhibiting shape coexistence. Mixing of configurations can be studied by measuring the monopole strength $\rho^2(E0)$, however, currently the experimental information is scarce and lacks precision, especially for the $I^\pi \rightarrow I^\pi$ ($I \neq 0$) transitions.
