/ Johnson, Jake D (Leuven U.) ; Heines, Michael (Leuven U.) ; Bruchertseifer, Frank (Geel, JRC) ; Chevallay, Eric (CERN) ; Cocolios, Thomas E (Leuven U.) ; Dockx, Kristof (Leuven U.) ; Duchemin, Charlotte (Leuven U. ; CERN) ; Heinitz, Stephan (SCK-CEN, Mol) ; Heinke, Reinhard (Leuven U. ; CERN) ; Hurier, Sophie (Leuven U. ; SCK-CEN, Mol) et al.
$^{225}$Ac is a radio-isotope that can be linked to biological vector molecules to treat certain distributed cancers using targeted alpha therapy. However, developing $^{225}$Ac-labelled radiopharmaceuticals remains a challenge due to the supply shortage of pure $^{225}$Ac itself. [...]

/CMS
A study of the $^{180}\mathrm{Hg}$ decay chain performed at the CERN-ISOLDE facility has allowed the ground-state–to–ground-state α decay of $^{180}\mathrm{Pt}$ to be investigated. A more precise α-decay branching ratio of $b_{\alpha}$ $(^{180}\mathrm{Pt})=0.52(5)$% has been deduced. [...]

First ion source at ISOL@MYRRHA with an improved thermal profile - Theoretical considerations

ISOL@MYRRHA will be a new Radioactive Ion Beam (RIB) facility in Belgium based on the Isotope Separation On-Line (ISOL) technique, and established within the framework of MYRRHA, the world’s first large-scale accelerator driven system project at power levels scalable to industrial systems. The surface ion source, or hot cavity, is chosen as initial source for its reliability and simple design. [...]

Hyperfine structure and isotope shifts have been measured for the ground and isomeric states in the neutron-deficient isotopes $^{179–184}Tl$ using the 276.9-nm transition. The experiment has been performed at the CERN-Isotope Separator On-Line facility using the in-source resonance-ionization laser spectroscopy technique. [...]

A Laser Ion Source and Trap (LIST) for a thick-target, isotope-separation on-line facility has been implemented at CERN ISOLDE for the production of pure, laser-ionized, radioactive ion beams. It offers two modes of operation, either as an ion guide, which performs similarly to the standard ISOLDE resonance ionization laser ion source (RILIS), or as a more selective ion source, where surface-ionized ions from the hot ion-source cavity are repelled by an electrode, while laser ionization is done within a radio-frequency quadrupole ion guide.

Laser spectroscopy of neutron-rich $^{207,208}$Hg isotopes: Illuminating the kink and odd-even staggering in charge radii across the $N=126$ shell closure
/ Day Goodacre, T. (Manchester U. ; CERN ; TRIUMF) ; Afanasjev, A.V. (Mississippi State U.) ; Barzakh, A.E. (St. Petersburg, INP) ; Marsh, B.A. (CERN) ; Sels, S. (CERN ; Leuven U.) ; Ring, P.

The mean-square charge radii of $^{207,208}$Hg ($Z=80, N=127,128$) have been studied for the first time and those of $^{202,203,206}$Hg ($N=122,123,126$) remeasured by the application of in-source resonance-ionization laser spectroscopy at ISOLDE (CERN). The characteristic \textit{kink} in the charge radii at the $N=126$ neutron shell closure has been revealed, providing the first information on its behavior below the $Z=82$ proton shell closure.
