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 Lamb shift experiment of the CREMA collaboration in muonic hydrogen
[1] and deuterium allowed to determine the proton radius and
other nuclear properties with an order of magnitude higher precision,
compared to spectroscopic measurements of ordinary hydrogen.
As a successor experiment, the determination of the Lamb shift in the
muonic helium ions mu3He+ and mu4He+ [2] will be a contribution to
solving the proton radius puzzle as well as the discrepancy in
electronic isotope-shift measurements.
On this poster, an overview of the achieved results of the CREMA
collaboration is presented and set into the context of the discrepancies
to other experimental findings.
Recent results from the measurements on helium isotopes during
spring/summer 2014 are included.
