Detailed spectroscopy of doubly magic $^{132}$Sn / IS610 Collaboration
The structure of the doubly magic $^{132}_{50}$Sn$_{82}$ has been investigated at the ISOLDE facility at CERN, populated both by the $\beta^-$ decay of $^{132}$In and $\beta^-$-delayed neutron emission of $^{133}$In. The level scheme of $^{132}$Sn is greatly expanded with the addition of 68 $\gamma$ transitions and 17 levels observed for the first time in the $\beta$ decay. [...]

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. [...]

Tin is the chemical element with the largest number of stable isotopes. Its complete proton shell, comparable with the closed electron shells in the chemically inert noble gases, is not a mere precursor to extended stability; since the protons carry the nuclear charge, their spatial arrangement also drives the nuclear electromagnetism [...]

Evolution of Octupole Deformation in Radium Nuclei from Coulomb Excitation of Radioactive $^{222}\mathrm{Ra}$ and $^{228}\mathrm{Ra}$ Beams / Butler, P.A. (U. Liverpool (main)) ; Gaffney, L.P. (U. Liverpool (main) ; CERN) ; Spagnoletti, P. (Paisley U.) ; Abrahams, K. (Western Cape U.) ; Bowry, M. (Paisley U. ; TRIUMF) ; Cederkäll, J. (Lund U.) ; de Angelis, G. (INFN, Legnaro) ; De Witte, H. (Leuven U.) ; Garrett, P.E. (Guelph U.) ; Goldkuhle, A. (Cologne U.) et al.
There is sparse direct experimental evidence that atomic nuclei can exhibit stable pear shapes arising from strong octupole correlations. In order to investigate the nature of octupole collectivity in radium isotopes, electric octupole ($E3$) matrix elements have been determined for transitions in $^{222,228}$Ra nuclei using the method of sub-barrier, multi-step Coulomb excitation.

First glimpse of the $N=82$ shell closure below $Z=50$ from masses of neutron-rich cadmium isotopes and isomers / Manea, V. (CERN ; Heidelberg, Max Planck Inst. ; Leuven U.) ; Karthein, J. (CERN ; Heidelberg, Max Planck Inst.) ; Atanasov, D. (Dresden, Tech. U.) ; Bender, M. (IP2I, Lyon) ; Blaum, K. (Heidelberg, Max Planck Inst.) ; Cocolios, T.E. (Leuven U.) ; Eliseev, S. (Heidelberg, Max Planck Inst.) ; Herlert, A. (FAIR, Darmstadt) ; Holt, J.D. (TRIUMF) ; Huang, W.J. (CSNSM, Orsay) et al.
We probe the $N=82$ nuclear shell closure by mass measurements of neutron-rich cadmium isotopes with the ISOLTRAP spectrometer at ISOLDE-CERN. The new mass of $^{132}$Cd offers the first value of the $N=82$, two-neutron shell gap below $Z=50$ and confirms the phenomenon of mutually enhanced magicity at $^{132}$Sn. [...]

Thermal annealing effects in polycrystalline EuTiO$_{3}$ and Eu$_{2}$Ti$_{2}$O$_{7}$ / IS611 Collaboration
Using time-differential perturbed angular correlation ofγrays, we investigated the electric-field gradient of polycrystalline EuTiO$_{3}$ and Eu$_{2}$Ti$_{2}$O$_{7}$, with $^{181}$Hf($^{181}$Ta) as a probe, following different thermal treatments. The measurements were performed at ISOLDE-CERN fol-lowing 80 keV implantation at the Bonn Radioisotope Separator. [...]

Alpha-PET for Prostate Cancer: Preclinical investigation using 149Tb-PSMA-617 / Umbricht, Christoph A.

(PSI, Villigen) ; Müller, Cristina (PSI, Villigen ; ETH, Zurich) ; Bernhardt, Peter (Chalmers U. Tech.) ; Koster, Ulli (Laue-Langevin Inst.)
In this study, it was aimed to investigate$^{149}$Tb-PSMA-617 for targeted α-therapy (TAT) using a mouse model of prostate-specific membrane antigen (PSMA)-expressing prostate cancer.$^{149}$Tb-PSMA-617 was prepared with >98% radiochemical purity (6 MBq/nmol) for the treatment of mice with PSMA-positive PC-3 PIP tumors.$^{149}$Tb-PSMA-617 was applied at 1 × 6 MBq (Day 0) or 2 × 3 MBq (Day 0 & Day 1 or Day 0 & Day 3) and the mice were monitored over time until they had reached a pre-defined endpoint which required euthanasia. The tumor growth was significantly delayed in mice of the treated groups as compared to untreated controls (p < 0.05). [...]

Search for the $^{73}\mathrm{Ga}$ ground-state doublet splitting in the $\beta$ decay of $^{73}\mathrm{Zn}$ / Vedia, V (UCM, Madrid, Dept. Phys.) ; Paziy, V (UCM, Madrid, Dept. Phys.) ; Fraile, L M (UCM, Madrid, Dept. Phys.) ; Mach, H (UCM, Madrid, Dept. Phys. ; NCBJ, Swierk) ; Walters, W B (Maryland U., Dept.

Estructura Materia) ; Bucher, B (Notre Dame U. ; LLNL, Livermore) ; Chiara, C J (Maryland U., Dept. Chem. ; Argonne, PHY) et al.
The existence of two close-lying nuclear states in $^{73}$Ga has recently been experimentally determined: a 1/2$^−$ spin-parity for the ground state was measured in a laser spectroscopy experiment, while a J$^{\pi} = 3/2^−$ level was observed in transfer reactions. This scenario is supported by Coulomb excitation studies, which set a limit for the energy splitting of 0.8 keV. [...]
