DESCRIPTION:Speakers: Thomas Cocolios (KU Leuven)\n\nNuclear charge radii 
 are known to be impactful to further our understanding of the nuclear land
 scape\, from kinks at magic numbers to onset of deformation or the dramati
 c odd-even staggering in the neutron-deficient mercury isotopes. Recent de
 velopments at CERN ISOLDE\, like the implementation of the Mainz-designed 
 Perpendicularly-Illuminated Laser Ion Source & Trap (PI-LIST) has enabled 
 the study of neutron-rich polonium and actinium isotopes\, helping delinea
 te the region of octupole deformation north-east of 208Pb.While laser spec
 troscopy gives access to changes in charge radii across long chains of iso
 topes\, those measurements rely on atomic parameters which determination f
 rom large-scale atomic calculations result in large systematic uncertainti
 es\, often obscuring the nuclear information. It is possible to benchmark 
 those laser spectroscopy data against absolute charge radii\, when those a
 re available. However\, given that none of the odd-Z elements nor any elem
 ent beyond Pb have more than 2 stable isotopes\, none of those have so far
  such data available.At the Paul Scherrer Institute in Villigen\, Switzerl
 and\, the muX collaboration has developed an approach to study muonic x ra
 ys for samples as small as 10 µg. This has enabled a new program\, named 
 ReferenceRadii\, exploring absolute charge radii from aluminium to curium.
  Recent highlights from PI-LIST and ReferenceRadii\, and their impact wil
 l be presented. \n\nhttps://indico.zdv.uni-mainz.de/event/96/
