Measurement of charge radii and moments of exotic nuclides — •Liss Vázquez Rodríguez for the COLLAPS collaboration — Max-Planck-Institut für Kernphysik, Heidelberg, Germany — European Organization for Nuclear Research, Geneve, Switzerland

COLLAPS (COLlinear LAser sPectroScopy) stands at ISOLDE as a pioneering setup in the field of laser spectroscopy. This experiment focuses on the measurement of distinctive nuclear properties of short-lived and exotic radioactive nuclei. These properties include nuclear spins, electromagnetic moments, and charge radii, which are extracted through the hyperfine structures and isotope shifts.

At the heart of COLLAPS's inquiry are fundamental questions about the nature of nuclear existence: What are the limits of nuclear existence? How do simple patterns emerge in complex nuclei? Are there new forms of structure far from stability? To address these questions, the COLLAPS team is dedicated to developing laser spectroscopy techniques of exceptional precision and sensitivity.

An overview of the COLLAPS setup will be given followed by a discussion of some recent results in the tin and lead region.
