Over 30 years ago isotope shifts and hyperfine structures of mercury and gold isotopes were measured by laser spectroscopy at ISOLDE [1,2,3]. Nuclear charge radii, spins, and magnetic and quadrupole moments were determined, revealing the sudden and unforeseen onset of shape staggering and deformation for the neutron-deficient isotopes, and sparking a great interest in this region of the...

In 2015, several beams were for the “first” time utilized for emission Mössbauer spectroscopy (eMS) studies at ISOLDE with applications in solid state physics and biophysics.
These include laser ionized $^{119}$In (2.1 min.) and $^{119}$Ag (2.1 s) for $^{119}$Sn eMS, $^{151}$Dy → $^{151}$Gd (120 d) for $^{151}$Eu eMS and $^{197}$Hg (62 h) for $^{197}$Au eMS.
I will present the newly...

Metal ions are essential to all living systems, and are for example involved in catalysis, regulation of gene expression, controlling and maintaining structure and folding of biomolecules, and electron transport. Inside cells the concentration of both essential and toxic metal ions is tightly controlled, and one facet of metallobiochemistry is the structure and function of various...

The shape coexistence in $^{181,183,185,187,189}$Au was investigated via $\beta^+$/EC decay of corresponding Hg isotopes. Samples of Hg isotopes were produced by deposition of low-energy beam from ISOLDE facility. For this purpose a new travelling setup, the TATRA tape transportation system was developed. It uses the metallic tape prepared by rapid quenching of alloy melt producing amorphous...

Barium isotopes are located in a region of the Segr\`e chart characterized by a variety of
shape phenomena, including shape coexistence and presence of static octupole deformations.
In this isotopic chain alternating-parity bands, with large and constant B(E1) transition moments,
have been found in $^{140-144}$Ba; the neighboring nucleus, $^{146}$Ba, shows instead slower E1 transition...

*On behalf of the MAGISOL, the IS507 and the IS541 collaborations*
I will present preliminary results from two decay-experiments, which were performed by the MAGISOL collaboration at ISOLDE in 2015.
The first experiment was a decay-study of $^{20,21}$Mg performed at the ISOLDE decay station. The beta-decays of $^{20,21}$Mg provide information about the beta-strength functions to states...
