Towards Precision Muonic X-Ray Measurements of Charge Radii of Light Nuclei

Ben Ohayon, Andreas Abeln, Silvia Bara +20

We propose an experiment to measure the nuclear charge radii of light elements with up to 20~times higher accuracy. These are essential both for understanding nuclear physics at lo…

The helion charge radius from laser spectroscopy of muonic helium-3 ions

The CREMA Collaboration, Karsten Schuhmann, Luis M. P. Fernandes +37

Hydrogen-like light muonic ions, in which one negative muon replaces all the electrons, are extremely sensitive probes of nuclear structure, because the large muon mass increases t…
