Combining laser spectroscopy in a Versatile Arc Discharge and Laser Ion Source, with Penning-trap mass spectrometry at the CERN-ISOLDE facility, this work reports on mean-square charge radii of neutron-rich mercury isotopes across the N=126 shell closure, the electromagnetic moments of 207Hg and more precise mass values of 206208Hg. The odd-even staggering (OES) of the mean square charge radii and the kink at N=126 are analyzed within the framework of covariant density functional theory (CDFT), with comparisons between different functionals to investigate the dependence of the results on the underlying single-particle structure. [...]

A comprehensive study of the isotope 178 Au has been made at the CERN-ISOLDE facility, using resonance laser ionization. Two long-lived states in 178 Au were identified—a low-spin ground state and a high-spin isomer—each of which were produced as pure beams. [...]
