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. [...]

First β-decay spectroscopy of $^{135}$In and new $β$-decay branches of $^{134}$In / IDS Collaboration
The $\beta$ decay of the neutron-rich $^{134}$In and $^{135}$In was investigated experimentally in order to provide new insights into the nuclear structure of the tin isotopes with magic proton number $Z=50$ above the $N=82$ shell. The $\beta$-delayed $\gamma$-ray spectroscopy measurement was performed at the ISOLDE facility at CERN, where indium isotopes were selectively laser-ionized and on-line mass separated. [...]

Low-spin states in $^{80}$Ge populated in the $\beta$ decay of the $^{80}$Ga $3^-$ isomer / Sekal, S (Algiers U. Sci. Tech. ; CERN) ; Fraile, L M (Madrid U.) ; Lică, R (CERN ; Bucharest, IFIN-HH) ; Borge, M J G (Madrid, Inst. Estructura Materia) ; Walters, W B (Maryland U., Dept. Chem.) ; Aprahamian, A (Notre Dame U.) ; Benchouk, C (Algiers U. Sci. Tech.) ; Bernards, C (Yale U. (main) ; Cologne U.) ; Briz, J A (Madrid, Inst. Estructura Materia) ; Bucher, B (Idaho Natl. Lab.) et al.
The structure of  $^{80}$Ge has been investigated at the ISOLDE facility at CERN. A previous study reported for the first time a low-lying $0^+_2$ intruder state at 639 keV, based on the coincidence with a previously unobserved 1764-keV $γ$ ray, and suggested it as evidence for shape coexistence in $^{80}$Ge.

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. [...]

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. [...]

Search for shape-coexisting 0$^+$ states in $^{66}$Ni from lifetime measurements / Olaizola, B (UCM, Madrid, Dept. Phys.) ; Fraile, L M (UCM, Madrid, Dept. Phys.) ; Mach, H (UCM, Madrid, Dept.

Estructura Materia) ; Cal-González, J (UCM, Madrid, Dept. Phys.) ; Ghiţa, D (Bucharest, IFIN-HH) ; Köster, U (Laue-Langevin Inst.) et al.
The lifetime of the 0$_3^+$ state in $^{66}$Ni, two neutrons below the $N=40$ subshell gap, has been measured. The transition $B(E2;0_3^+ \rightarrow 2_1^+)$ is one of the most hindered E2 transitions in the Ni isotopic chain and it implies that, unlike $^{68}$Ni, there is a spherical structure at low excitation energy.

Lifetimes and shape-coexisting states of $^{99}Zr$ / Spagnoletti, P (West Scotland U.) ; Simpson, G (LPSC, Grenoble) ; Kisyov, S (Bucharest, IFIN-HH) ; Bucurescu, D (Bucharest, IFIN-HH) ; Régis, J M (Cologne U.) ; Saed-Samii, N (Cologne U.) ; Blanc, A (Laue-Langevin Inst.) ; Jentschel, M (Laue-Langevin Inst.) ; Köster, U (Laue-Langevin Inst.) ; Mutti, P (Laue-Langevin Inst.) et al.
Lifetimes of intermediate-spin states in two rotational bands of $^{99}Zr$ have been measured. These states were populated following the neutron-induced fission of $^{235}U$ at the PF1B beamline of the Institut Laue-Langevin, Grenoble, during the EXILL-FATIMA campaign. [...]

Evolution of deformation in neutron-rich Ba isotopes up to $A=150$ / Lică, R (CERN ; Bucharest, IFIN-HH) ; Benzoni, G (INFN, Milan) ; Rodríguez, T R (Madrid, Autonoma U.) ; Borge, M J G (CERN ; CSIC, Madrid) ; Fraile, L M (UCM, Somosaguas) ; Mach, H (NCBJ, Warsaw) ; Morales, A I (INFN, Milan ; Milan U. ; Valencia U., IFIC) ; Madurga, M (CERN) ; Sotty, C O (Leuven U.) ; Vedia, V (UCM, Somosaguas) et al. /IDS
The occurrence of octupolar shapes in the Ba isotopic chain was recently established experimentally up to $N=90$. To further extend the systematics, the evolution of shapes in the most neutron-rich members of the $Z=56$ isotopic chain accessible at present, $^{148,150}$Ba, has been studied via $\beta$ decay at the ISOLDE Decay Station.

The low energy structure of 66Fe was studied by means of γ- and fast-timing spectroscopy at the ISOLDE/CERN facility. The level scheme of 66Fe populated following the decay of 66Mn was established. [...]
