208Po populated through EC/β+decay
The structure of 208Po resulting from the EC/β + decay of 208At was studied at
CERN’s ISOLDE Decay Station (IDS). The high statistics afforded by the high yield of 208At and the high efficiency HPGe clusters at the IDS allowed for greater insight into lower intensity transitions and thus significant expansion of the 208Po level scheme. Furthermore, investigation into the isomeric state yielded a new half life 377(9) ns in addition to uncovering new transitions populating the state.The research leading to these results has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement no. 654002.

Collectivity of Po-196 at low spin
Absolute electromagnetic transition probabilities in Po-196 have been measured using the recoil distance Doppler-shift technique. The lifetimes of the three lowest yrast states in Po-196 were extracted from singles gamma-ray spectra by using the recoil-decay tagging method. In addition, configuration mixing calculations of angular momentum projected mean-field states have been carried out for Po-196. The present study sheds light on the onset of collectivity and mixing of competing structures in neutron-deficient Po nuclei

Application of ultra-fast timing techniques to the study of exotic and weakly produced nuclei
Ultra-fast time-delayed techniques have been recently applied in a number of studies where exotic nuclei were identified using advanced selection techniques. These include large Compton-suppressed Ge arrays, in-flight separators or recoil separators. Some of the new results are discussed in this presentation. Besides the results for Mg and Pd, they include the first determination of the half-life of the state in Ge, = 2.95(6) ns, and significantly more precise results for Mn (3680 keV level) and V (421 keV level), = 1760(40) ps and 135 ps, respectively. Development of new scintillators will steadily improve precision and sensitivity of future measurements
