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. [...]

Coulomb excitation of pear-shaped nuclei
/ Butler, Peter (Liverpool U.) ; Gaffney, Liam (Liverpool U. ; CERN) ; Spagnoletti, Pietro (West Scotland U.) ; Konki, Joonas (CERN) ; Scheck, Marcus (West Scotland U.) ; Smith, John (West Scotland U.) ; Abrahams, Kenzo (Western Cape U.) ; Bowry, Michael (TRIUMF) ; Cederkäll, Joakim (Lund U.) ; Chupp, Timothy (Michigan U.) et al.
There is a large body of evidence that atomic nuclei can undergo octupole distortion and assume the shape of a pear. This phenomenon is important for measurements of electric-dipole moments of atoms, which would indicate CP violation and hence probe physics beyond the Standard Model of particle physics. [...]

Coulomb excitation of $^{222}$Rn
/ Spagnoletti, P (West Scotland U. ; Simon Fraser U., Dept. Chem.) ; Butler, P A (Liverpool U.) ; Gaffney, L P (Liverpool U. ; CERN) ; Abrahams, K (Western Cape U.) ; Bowry, M (West Scotland U. ; TRIUMF) ; Cederkäll, J (Lund U.) ; Chupp, T (U. Michigan, Ann Arbor) ; de Angelis, G (INFN, Legnaro) ; De Witte, H (Leuven U.) ; Garrett, P E (Guelph U.) et al.
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. [...]

An exploratory experiment performed at REX-ISOLDE to investigate cluster-transfer reactions with radioactive beams in inverse kinematics is presented. The aim of the experiment was to test the potential of cluster-transfer reactions at the Coulomb barrier as a mechanism to explore the structure of exotic neutron-rich nuclei. [...]

Shape dynamics in neutron-rich Kr isotopes: Coulomb excitation of $^{92}Kr$, $^{94}Kr$ and $^{96}Kr$

We report on the study of excited states in $^{92,94,96}Kr$ populated via projectile Coulomb excitation at safe energies. The radioactive ion beams at energies of 2.85 MeV/u were delivered by the REX-ISOLDE facility at CERN and impinged on self-supporting $^{194,196}Pt$ targets. [...]
