Coulomb excitation of Zn74,76
/ ISOLDE Collaboration
The first experiment using radioactive beams post-accelerated by the HIE-ISOLDE facility has enabled to obtain a precise set of B(E2) transition probabilities in neutron-rich Zn74,76 isotopes. The resulting B(E2; 21+→01+) values are consistent with those determined in earlier REX-ISOLDE measurements. [...]

In the present study, $B(E2, 2^{+1}\rightarrow 0^{+1})$ values have been measured in the$^{208,210}$Rn and$^{206}$Po nuclei through Coulomb excitation of re-accelerated radioactive beams in inverse kinematics at CERN-ISOLDE. These nuclei have been proposed to lie in, or at the boundary of the region where the seniority scheme should persist. [...]

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.

The electron spectrometer, SPEDE, has been developed and will be employed in conjunction with the Miniball spectrometer at the HIE-ISOLDE facility, CERN. SPEDE allows for direct measurement of internal conversion electrons emitted in-flight, without employing magnetic fields to transport or momentum filter the electrons. [...]

Octupole states in $^{207}$Tl studied through $β$ decay

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. [...]

The nature of quadrupole and octupole collectivity in $^{222}$Rn was investigated by determining the electric-quadrupole (E2) and octupole (E3) matrix elements using subbarrier, multistep Coulomb excitation. The radioactive $^{222}$Rn beam, accelerated to 4.23 MeV/u, was provided by the HIE-ISOLDE facility at CERN. [...]

States in the $N=28$ nucleus $^{46}$Ar have been studied by a two-neutron transfer reaction at REX-ISOLDE (CERN). A beam of radioactive $^{44}$ at an energy of 2.16~AMeV and a tritium loaded titanium target were used to populate $^{46}$ by the t($^{44}$,p) two-neutron transfer reaction. [...]

/MINIBALL ; HIE-ISOLDE
The first $2^+$ and $3^-$ states of the doubly magic nucleus $^{132}$Sn are populated via safe Coulomb excitation employing the recently commissioned HIE-ISOLDE accelerator at CERN in conjunction with the highly efficient MINIBALL array. The $^{132}$Sn ions are accelerated to an energy of 5.49 MeV/nucleon and impinged on a $^{206}$Pb target. [...]

Astron. ; SCK-CEN, Mol) ; Fedosseev, V N (CERN) et al.
The structure of low-spin states originating from shape-coexisting configurations in $^{68}_{40}$Ni$_{28}$ was directly probed via the two-neutron transfer reaction $^{66}$Ni$(t,p)^{68}$Ni in inverse kinematics using a radioactive ion beam on a radioactive target. The direct feeding to the first excited 0$^+$ state was measured for center-of-mass angles 4°–16° and amounts to an integral of 4.2(16)% relative to the ground state. [...]
