Abstract
Precision spectroscopy of light muonic atoms provides unique information
about the atomic and nuclear structure of these systems and thus represents a way to
access fundamental interactions, properties and constants. One application comprises the determination of absolute nuclear charge radii with unprecedented accuracy from measurements of the 2S - 2P Lamb shift. Here, we review recent results of nuclear charge radii extracted from muonic hydrogen and helium spectroscopy and present experiment proposals to access light muonic atoms with Z 3. In addition, our approaches towards a precise measurement of the Zemach radii in muonic hydrogen (p) and helium (3He+) are discussed. These results will provide new tests of bound-state quantum-electrodynamics in hydrogen-like systems and can be used as benchmarks for nuclear structure theories.
