Description
Muonic atoms have an increased sensitivity on finite size effects of the
nucleus due to the ~200-fold mass of the muon compared to the electron.
The CREMA collaboration has measured the Lamb shift in muonic hydrogen
and muonic deuterium atoms, as well as in muonic helium-4 and helium-3 ions.
These measurements allow to determine charge radii and other nuclear
properties
with improved precision compared to previously conducted measurements.
Contributions to solving the proton radius puzzle as well as the discrepancy
in electronic isotope-shift measurements from the collected data will be
discussed.
A status update of CREMA's ongoing data analysis towards charge radius
extractions
of the deuteron, helion, and the alpha particle will be given.
Current analysis-related topics such as theory issues and possible
systematics
will be shown,
together with an outlook for possible future measurements using bound muonic
systems.
