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. [...]

Study of exotic decay of Cs isotope close to the proton drip line
/ Das, P (Saha Inst. ; HBNI, Mumbai) ; Datta, Ushasi (Saha Inst. ; HBNI, Mumbai) ; Chakraborty, S (Saha Inst. ; Unlisted, IN) ; Rahman, A (Saha Inst. ; Unlisted, IN) ; Borge, M J G (Madrid, Inst.

Estructura Materia) ; Bhattacharya, P (Saha Inst.) ; Bhattacharyya, A (Saha Inst. ; HBNI, Mumbai) et al.
The neutron-deficient $^{115}$Cs was produced at ISOLDE, CERN by spallation reaction using 1.4 GeV proton on LaC2 target. The exotic decay modes were studied by using a charged particle array (DSSD and pad detectors) and a γ-detector array (four Clovers) at the ISOLDE decay station (IDS). [...]

$^{208}$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.

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. [...]

Competition between Allowed and First-Forbidden $β$ Decay: The Case of $^{208}$Hg$→^{208}$Tl
/ Carroll, R J (Surrey U.) ; Podolyák, Zs (Surrey U. ; Darmstadt, GSI) ; Berry, T (Surrey U.) ; Grawe, H (Darmstadt, GSI) ; Alexander, T (Surrey U.) ; Andreyev, A N (York U., England ; JAEA, Ibaraki) ; Ansari, S (Cologne U.) ; Borge, M J G (CERN) ; Brunet, M (Surrey U.) ; Creswell, J R (Liverpool U.) et al.
The $β$ decay of $^{208}$Hg into the one-proton hole, one neutron-particle $^{208}_{81}$Tl$_{127}$ nucleus was investigated at CERN-ISOLDE. Shell-model calculations describe well the level scheme deduced, validating the proton-neutron interactions used, with implications for the whole of the N>126, Z<82 quadrant of neutron-rich nuclei.

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. [...]
