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.

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.

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. [...]

Investigation of Low-lying States in $^{133}$Sn Populated in the $\beta $ Decay of $^{133}$In Using Isomer-selective Laser Ionization / IS610 Collaboration
Excited states in the neutron-rich isotope 133Sn were studied via the β decay of 133In. Isomer selective ionization using the ISOLDE RILIS enabled the β decays of 133Ings (I π = 9/2 +) and 133mIn (I π = 1/2 −) to be studied independently for the first time. [...]

Background: Shell evolution can impact the structure of the nuclei and lead to effects such as shape coexistence. The nuclei around $^{68}$Ni represent an excellent study case, however, spectroscopic information of the neutron-rich, $Z<28$ nuclei is limited. [...]

Fast-timing study of the $l$-forbidden $1/2^+ \rightarrow 3/2^+ M1$ transition in $^{129}Sn$ / Lică, R (CERN ; Bucharest, IFIN-HH) ; Mach, H (Warsaw, Inst. Nucl.

The levels in Sn129 populated from the β− decay of In129 isomers were investigated at the ISOLDE facility of CERN using the newly commissioned ISOLDE Decay Station (IDS). The lowest 1/2+ state and the 3/2+ ground state in Sn129 are expected to have configurations dominated by the neutron s1/2 (l=0) and d3/2 (l=2) single-particle states, respectively. [...]

Characterization of the low-lying 0$^{+}$ and 2$^{+}$ states in $^{68}$Ni via $\beta$ decay of the low-spin $^{68}$Co isomer / Flavigny, F ; Pauwels, D ; Radulov, D ; Darby, I J ; De Witte, H ; Diriken, J ; Fedorov, D V ; Fedosseev, V N (CERN) ; Fraile, L M ; Huyse, M et al.
The low-energy structure of the neutron-rich nucleus Ni68 has been investigated by measuring the β decay of the low-spin isomer in Co68 selectively produced in the decay chain of Mn68. A revised level scheme has been built based on the clear identification of β-γ-E0 delayed coincidences. [...]
