Shape coexistence in $^{180}$Hg studied through the $\beta$ decay of $^{180}$Tl
/ Elseviers, J (Leuven U.) ; Tsekhanovich, I (CENBG, Gradignan) ; Diriken, J (Leuven U.) ; Patronis, N (Leuven U. ; Ioannina U.) ; Koster, U (Laue-Langevin Inst.) ; Franchoo, S (Orsay, IPN) ; Vermote, S (Gent U.) ; Bree, N (Leuven U.) ; Veselsky, M (Bratislava, Inst. Phys.) ; Huyse, M (Leuven U.) et al.
The beta(+)/EC decay of (180)Tl and excited states in the daughter nucleus (180)Hg have been investigated at the CERN On-Line Isotope Mass Separator (ISOLDE) facility. Many new low-lying energy levels were observed in (180)Hg, of which the most significant are the 0(2)(+) at 419.6 keV and the 2(2)(+) at 601.3 keV. [...]

Combined in-beam electron and gamma-ray spectroscopy of (184,186)Hg
/ Scheck, M (Liverpool U.) ; Jones, P (Jyvaskyla U.) ; Rahkila, P (Jyvaskyla U.) ; Butler, P A (Liverpool U.) ; Larsen, A C (Oslo U.) ; Sandzelius, M (Jyvaskyla U.) ; Scholey, C (Jyvaskyla U.) ; Carrol, R J (Liverpool U.) ; Papadakis, P (Liverpool U.) ; Jakobsson, U (Jyvaskyla U.) et al.
By exploiting the SAGE spectrometer a simultaneous measurement of conversion electrons and gamma rays emitted in the de-excitation of excited levels in the neutron-deficient nuclei (184,186)Hg was performed. The light Hg isotopes under investigation were produced using the 4n channels of the fusion-evaporation reactions of (40)Ar and (148,150)Sm. [...]

Electromagnetic properties of low-lying states in neutron-deficient Hg isotopes: Coulomb excitation of $^{182}$Hg, $^{184}$Hg, $^{186}$Hg and $^{188}$Hg
/ 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.

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. [...]
