Chemical Purification of Terbium-155 from Pseudo-Isobaric Impurities in a Mass Separated Source Produced at CERN
/ Webster, Ben (Teddington, Natl. Phys. Lab ; Surrey U.) ; Ivanov, Peter (Teddington, Natl. Phys. Lab) ; Russell, Ben (Teddington, Natl. Phys. Lab) ; Collins, Sean (Teddington, Natl. Phys. Lab) ; Stora, Thierry (CERN) ; Ramos, Joao Pedro (CERN ; Leuven U.) ; Köster, Ulli (Laue-Langevin Inst.) ; Robinson, Andrew Paul (Teddington, Natl. Phys. Lab ; Manchester U.) ; Read, David (Teddington, Natl. Phys. Lab ; Surrey U.)
Four terbium radioisotopes ($^{149, 152, 155, 161}$Tb) constitute a potential theranostic quartet for cancer treatment but require any derived radiopharmaceutical to be essentially free of impurities. Terbium-155 prepared by proton irradiation and on-line mass separation at the CERN-ISOLDE and CERN-MEDICIS facilities contains radioactive$^{139}$Ce$^{16}$O and also zinc or gold, depending on the catcher foil used.

$^{208}$Po populated through EC/β$^{+}$ decay
/ Brunet, M (Surrey U.) ; Berry, T A (Surrey U.) ; Podolyák, Zs (Surrey U.) ; Carroll, R J (Surrey U.) ; Lica, R (CERN ; Bucharest, IFIN-HH) ; Sotty, Ch (Bucharest, IFIN-HH ; Leuven U.) ; Andreyev, A N (York U., England) ; Borge, M J G (CERN) ; Cubiss, J G (CERN ; York U., England) ; Fraile, L M (Madrid U.) et al.
The structure of $^{208}$Po resulting from the EC/β + decay of $^{208}$At was studied at CERN’s ISOLDE Decay Station (IDS). The high statistics afforded by the high yield of $^{208}$At and the high efficiency HPGe clusters at the IDS allowed for greater insight into lower intensity transitions and thus significant expansion of the $^{208}$Po level scheme.

Dealing with contaminants in Coulomb excitation of radioactive beams
/ Morrison, L (Surrey U.) ; Hadynska-Klek, K (Warsaw U. (main) ; Surrey U.) ; Podolyák, Zs (Surrey U.) ; Gaffney, L P (Liverpool U. ; CERN) ; Kaya, L (Cologne U.) ; Berry, T (Surrey U.) ; Boukhari, A (Orsay) ; Brunet, M (Surrey U.) ; Canavan, R (Surrey U. ; Teddington, Natl. Phys. Lab) ; Catherall, R (CERN) et al.
Data analysis of the Coulomb excitation experiment of the exotic $^{206}$Hg nucleus, recently performed at CERN’s HIE-ISOLDE facility, needs to account for the contribution to target excitation due to the strongly-present beam contaminant $^{130}$Xe. In this paper, the contamination subtraction procedure is presented..

The $\nu$-ball is a high-efficiency hybrid spectrometer which consists of both germanium (Ge) detectors and associated anti-Compton BGO shields, coupled to lanthanum bromide (LaBr$_3$) detectors. The hybrid configuration provides a combination of both excellent energy and timing resolutions. [...]

CERN-MEDICIS: A Review Since Commissioning in 2017
/ MEDICIS Collaboration
The CERN-MEDICIS (MEDical Isotopes Collected from ISolde) facility has delivered its first radioactive ion beam at CERN (Switzerland) in December 2017 to support the research and development in nuclear medicine using non-conventional radionuclides. Since then, fourteen institutes, including CERN, have joined the collaboration to drive the scientific program of this unique installation and evaluate the needs of the community to improve the research in imaging, diagnostics, radiation therapy and personalized medicine.

Competition between allowed and first-forbidden $β$ decays of $^{208}$At and expansion of the $^{208}$Po level scheme
/ Brunet, M (Surrey U.) ; Podolyák, Zs (Surrey U.) ; Berry, T A (Surrey U.) ; Brown, B A (Michigan State U., NSCL) ; Carroll, R J (Surrey U.) ; Lica, R (CERN ; Bucharest, IFIN-HH) ; Sotty, Ch (Bucharest, IFIN-HH ; Leuven U.) ; Andreyev, A N (York U., England ; JAEA, Ibaraki) ; Borge, M J G (CERN) ; Cubiss, J G (CERN ; Madrid U.) et al.
The structure of $^{208}$Po populated through the EC/$β^+$ decay of $^{208}$At is investigated using $γ$-ray spectroscopy at the ISOLDE Decay Station. The presented level scheme contains 27 new excited states and 43 new transitions, as well as a further 50 previously observed $γ$ rays which have been (re)assigned a position. [...]

Quadrupole deformation of $^{130}$Xe measured in a Coulomb-excitation experiment
/ Morrison, L (Surrey U.) ; Hadyńska-Klȩk, K (Warsaw U., Heavy Ion Lab ; Surrey U.) ; Podolyák, Zs (Surrey U.) ; Doherty, D T (Surrey U.) ; Gaffney, L P (Liverpool U. ; CERN) ; Kaya, L (Cologne U.) ; Próchniak, L (Warsaw U., Heavy Ion Lab) ; Samorajczyk-Pyśk, J (Warsaw U., Heavy Ion Lab) ; Srebrny, J (Warsaw U., Heavy Ion Lab) ; Berry, T (Surrey U.) et al.
Low-lying states in the isotope $^{130}$Xe were populated in a Coulomb-excitation experiment performed at CERN's HIE-ISOLDE facility. The magnitudes and relative signs of seven $E2$ matrix elements and one $M1$ matrix element coupling five low-lying states in $^{130}$Xe were determined using the semiclassical coupled-channel Coulomb-excitation least-squares search code gosia.

Octupole states in $^{207}$Tl studied through $β$ decay
/ Berry, T A (Surrey U.) ; Podolyák, Zs (Surrey U.) ; Carroll, R J (Surrey U.) ; Lică, R (CERN ; Bucharest, IFIN-HH) ; Brown, B A (Michigan State U.) ; Grawe, H (Darmstadt, GSI) ; Sotty, Ch (Bucharest, IFIN-HH ; Leuven U.) ; Timofeyuk, N K (Surrey U.) ; Alexander, T (Surrey U.) ; Andreyev, A N (York U., England) et al.
The $β$ decay of $^{207}$Hg into the single-proton-hole nucleus $^{207}$Tl has been studied through $γ$-ray spectroscopy at the ISOLDE Decay Station (IDS) with the aim of identifying states resulting from coupling of the $πs^{−1}_{1/2}, πd^{−1}_{3/2},$ and $πh^{−1}_{11/2}$ shell model orbitals to the collective octupole vibration. Twenty-two states were observed lying between 2.6 and 4.0 MeV, eleven of which were observed for the first time, and 78 new transitions were placed. [...]

Investigation of the $\Delta n = 0$ selection rule in Gamow-Teller transitions: The $\beta$-decay of $^{207}$Hg
/ Berry, T A (Surrey U.) ; Podolyák, Zs (Surrey U.) ; Carroll, R J (Surrey U.) ; Lică, R (CERN ; Bucharest, IFIN-HH) ; Grawe, H ; Timofeyuk, N K (Surrey U.) ; Alexander, T (Surrey U.) ; Andreyev, A N (York U., England) ; Ansari, S (Cologne U.) ; Borge, M J G (CERN ; Madrid, Inst. Estructura Materia) et al.
Gamow-Teller $\beta$ decay is forbidden if the number of nodes in the radial wave functions of the initial and final states is different. This $\Delta n=0$ requirement plays a major role in the $\beta$ decay of heavy neutron-rich nuclei, affecting the nucleosynthesis through the increased half-lives of nuclei on the astrophysical $r$-process pathway below both $Z=50$ (for $N>82$ ) and $Z=82$ (for $N>126$).
