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.\nWhile laser sp
 ectroscopy gives access to changes in charge radii across long chains of i
 sotopes\, those measurements rely on atomic parameters which determination
  from large-scale atomic calculations result in large systematic uncertain
 ties\, often obscuring the nuclear information. It is possible to benchmar
 k those laser spectroscopy data against absolute charge radii\, when those
  are available. However\, given that none of the odd-Z elements nor any el
 ement beyond Pb have more than 2 stable isotopes\, none of those have so f
 ar such data available.\nAt the Paul Scherrer Institute in Villigen\, Swit
 zerland\, the muX collaboration has developed an approach to study muonic 
 x rays for samples as small as 10 µg. This has enabled a new program\, na
 med ReferenceRadii\, exploring absolute charge radii from aluminium to cur
 ium. \nRecent highlights from PI-LIST and ReferenceRadii\, and their impa
 ct will be presented.\n\nhttps://indico.zdv.uni-mainz.de/event/96/
