/ Wrzosek-Lipska, K (Warsaw U., Heavy Ion Lab ; Leuven U.) ; Rezynkina, K (Leuven U. ; U. Strasbourg) ; Bree, N (Leuven U.) ; Zielińska, M (Warsaw U., Heavy Ion Lab ; IRFU, Saclay) ; Gaffney, L P (Liverpool U. ; Leuven U. ; CERN ; West Scotland U.) ; Petts, A (Liverpool U.) ; Andreyev, A (Leuven U. ; York U., England) ; Bastin, B (Leuven U. ; GANIL) ; Bender, M (Lyon, IPN) ; Blazhev, A (Cologne U.) et al.
The neutron-deficient mercury isotopes serve as a classical example of shape coexistence, whereby at low energy near-degenerate nuclear states characterized by different shapes appear. The electromagnetic structure of even-mass $^{182-188}$ Hg isotopes was studied using safe-energy Coulomb excitation of neutron-deficient mercury beams delivered by the REX-ISOLDE facility at CERN.

Low-energy Coulomb excitation of $^{96,98}$Sr beams
/ Clément, E (GANIL ; CERN) ; Zielińska, M (IRFU, Saclay ; Warsaw U., Heavy Ion Lab) ; Péru, S (CEA DAM) ; Goutte, H (IRFU, Saclay) ; Hilaire, S (CEA DAM) ; Görgen, A (Oslo U.) ; Korten, W (IRFU, Saclay) ; Doherty, D T (IRFU, Saclay ; York U., England) ; Bastin, B (GANIL) ; Bauer, C (Darmstadt, Tech. U.) et al.
The structure of neutron-rich $^{96,98}$Sr nuclei was investigated by low-energy safe Coulomb excitation of radioactive beams at the REX-ISOLDE facility, CERN, with the MINIBALL spectrometer. A rich set of transitional and diagonal E2 matrix elements, including those for non-yrast structures, has been extracted from the differential Coulomb-excitation cross sections. [...]

Onset of collectivity in $^{96,98}$Sr studied via Coulomb excitation

A rapid onset of quadrupole deformation is known to occur around the neutron number 60 in the neutron-rich Zr and Sr isotopes. This shape change has made the neutron-rich A = 100 region an active area of experimental and theoretical studies for many decades now. [...]

Shape Coexistence in the Neutron-Deficient Even-Even $^{182-188}$Hg Isotopes Studied via Coulomb Excitation
/ Bree, N (KU Leuven, Dept. Phys. Astron.) ; Wrzosek-Lipska, K (KU Leuven, Dept. Phys. Astron.) ; Petts, A (U. Liverpool (main)) ; Andreyev, A (KU Leuven, Dept. Phys. Astron.) ; Bastin, B (KU Leuven, Dept. Phys. Astron. ; GANIL) ; Bender, M (CENBG, Gradignan) ; Blazhev, A (Cologne U.) ; Bruyneel, B (Cologne U.) ; Butler, P A (U. Liverpool (main)) ; Butterworth, J et al.
Coulomb-excitation experiments to study electromagnetic properties of radioactive even-even Hg isotopes were performed with 2.85 MeV/nucleon mercury beams from REX-ISOLDE. Magnitudes and relative signs of the reduced E2 matrix elements that couple the ground state and low-lying excited states in Hg182-188 were extracted. [...]

(Liverpool U.) ; Cocolios, T.E. (CERN ; Manchester U.) et al.
Background: Shape coexistence in heavy nuclei poses a strong challenge to state-of-the-art nuclear models, where several competing shape minima are found close to the ground state. A classic region for investigating this phenomenon is in the region around $Z=82$ and the neutron mid-shell at $N=104$. [...]
