This project aims to measure the Lamb shift in muonic helium ions to achieve a more accurate determination of nuclear charge radii. It addresses the 'proton size puzzle' and seeks to improve understanding of nuclear structure and fundamental physics.
A measurement of the 2S-2P transition frequencies (Lamb shift) in the muonic helium-3 and 4 ions by means of laser spectroscopy is proposed.
This will lead to a ten times more accurate determination of the root-mean-square (rms) charge radii of the He-3 and He-4 nuclei.
The radius of the magnetic moment distribution inside the He-3 nucleus will result from the hyperfine structure in muonic 3He.In the muonic helium ion, a single negative muon orbits the helium nucleus.
The muon is a point-like l…
