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.

A technique for elucidating $\beta$-decay schemes of isotopes with a large density of states at low excitation energy has been developed, in which a Broad Energy Germanium (BEGe) detector is used in conjunction with coaxial hyper-pure germanium detectors. The power of this technique is demonstrated using the example of $^{183}$Hg decay. [...]

The ground states of /sup 176-86/Pt : an example of a shell model intruder state configuration
/ Wood, J L (School of Phys, Georgia Inst of Technol, Atlanta, GA, USA)
The systematics of excited states in the neutron-deficient even-mass Pt isotopes are shown to provide evidence that a strongly deformed configuration is present in the ground states of these isotopes. This configuration is proposed to be due to ( pi h/sub 9/2/)/sup 2/, based on proton intruder state systematics and the importance of valence neutrons and protons in producing deformation. [...]
