Detailed study of the decay of $^{21}$Mg / IS507 Collaboration
Beta-delayed proton and gamma emission in the decay of $^{21}$Mg has been measured at ISOLDE, CERN with the ISOLDE Decay Station (IDS) set-up. The existing decay scheme is updated, in particular what concerns proton transitions to excited states in $^{20}$Ne. [...]

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. [...]

Nuclear Level Density and $\gamma$-ray Strength Function of $^{67}\mathrm{Ni}$ and the impact on the i-process / ISOLDE Collaboration
Proton-$\gamma$ coincidences from $(\mathrm{d},\mathrm{p})$ reactions between a $^{66}\mathrm{Ni}$ beam and a deuterated polyethylene target have been analyzed with the inverse-Oslo method to find the nuclear level density (NLD) and $\gamma$-ray strength function ($\gamma$SF) of $^{67}\mathrm{Ni}$.

Structural formation yield of GeV centers from implanted Ge in diamond / Wahl, Ulrich (IST, Lisbon (main)) ; Correia, João Guilherme (IST, Lisbon (main)) ; Costa, Ângelo (Leuven U.) ; Lamelas, Afonso (Aveiro U.) ; Amaral, Vítor (Aveiro U.) ; Johnston, Karl (CERN) ; Magchiels, Goele (Leuven U.) ; Tunhuma, Shandirai Malven (Leuven U.) ; Vantomme, André (Leuven U.) ; Pereira, Lino M C (Leuven U.)
In order to study the structural formation yield of germanium-vacancy (GeV) centers from implanted Ge in diamond, we have investigated its lattice location by using the β$^{−}$ emission channeling technique from the radioactive isotope $^{75}$Ge (t$_{1/2}$ = 83 min) produced at the ISOLDE/CERN facility. $^{75}$Ge was introduced via recoil implantation following 30 keV ion implantation of the precursor isotope $^{75}$Ga (126 s) with fluences around 2 × 10$^{12}$–5 × 10$^{13}$ cm$^{−2}$.

Diffusion of Implanted 195Au Radiotracer Atoms in Amorphous Silicon under Irradiation with 1 Mev-N+ Ions / Voss, T (Stuttgart, Max Planck Inst.) ; Scharwaechter, P (Stuttgart, Max Planck Inst.) ; Frank, W (Stuttgart, Max Planck Inst. ; CERN) /ISOLDE Collaboration
The diffusion of implanted $^{195}$Au in Au-doped amorphous Si was studied, partly under N$^+$-irradiation by means of a radiotracer technique, in which the serial sectioning of the specimens was done by Ar$^+$-beam sputtering. It was found that high implantation doses in combination with great diffusion lengths give rise to complicated shapes of the diffusion profiles. [...]

Terbium-149 production: a focus on yield and quality improvement towards preclinical application / Favaretto, C (Basel U. ; PSI, Villigen) ; Grundler, P V (PSI, Villigen) ; Talip, Z (PSI, Villigen) ; Köster, U (Laue-Langevin Inst. ; CERN) ; Johnston, K (CERN) ; Busslinger, S D (PSI, Villigen) ; Sprung, P (PSI, Villigen) ; Hillhouse, C C (PSI, Villigen) ; Eichler, R (PSI, Villigen ; Bern U.) ; Schibli, R (PSI, Villigen ; Zurich, ETH) et al.
Terbium-149 (T$_{1/2}$ = 4.1 h, E$_{α}$ = 3.98 MeV (16.7%), 28 µm range in tissue) is a radionuclide with potential for targeted alpha therapy. Due to the negligible emission of α-emitting daughter nuclides, toxicity to healthy tissue may be reduced in comparison with other α-particle emitters. [...]
