Precise nuclear charge radii and beyond

Jan 26, 2026, 2:40 PM → Jan 30, 2026, 3:00 PM Europe/Berlin

Zentraler Seminarraum (Max Planck Institut Kernphysik, Heidelberg)

Natalia S. Oreshkina, Fabian Heiße (MHKP)

The workshop focuses on determining nuclear radii for medium to heavy nuclei and related topics.
We aim to bring together theorists from nuclear physics, atomic physics, and QED, alongside experimentalists working with diverse techniques such as muonic atoms, scattering, and isotope shifts.
The goal is to bridge these fields and methodologies, highlight current challenges and new ideas, and continue building a broad community towards improved nuclear radii.
