DESCRIPTION:Speakers: Kathrin Wimmer (Univ. Cologne)\n\nThe atomic nucleus
  is governed by a subtle\, almost perfect symmetry: the near-interchangeab
 ility of protons and neutrons\, called isospin symmetry. Conserving isospi
 n\, the physics of mirror nuclei\, pairs where the numbers of protons and 
 neutrons are swapped\, would be identical. \nHowever\, the small electroma
 gnetic force and other subtle effects break this symmetry\, offering a win
 dow into the inner workings of the nucleus.\nIn this talk\, I will present
  recent experimental studies that use electromagnetic transition rates as 
 a stringent and model-independent test of isospin symmetry. We observed a 
 striking breakdown of this symmetry in the mirror nuclei with mass number 
 70: instead of being identical\, 70Kr is significantly more deformed than 
 its mirror 70Se. In stark contrast\, a second study of the lighter A=62 nu
 clei shows perfect agreement with isospin symmetry predictions\, making it
  the most precise test of its kind to date. These results illustrate how s
 mall symmetry violations can result in large nuclear structure changes and
  dramatically different deformations.\n \n \n\nhttps://indico.gsi.de/eve
