Session 3: Exotic atoms
- Vladimir Korobov (Joint Institute for Nuclear Research (JINR))
The CERN Antiproton Decelerator, the only source of low-energy cooled antiproton beams in the world, will be extended by the ELENA storage ring to provide even lower energy antiprotons, thus increasing the number of antiprotons trapped in charged-particle traps or low density gas. The antiprotons are used for precision measurement or to form antihydrogen, the simplest anti-atom consisting of...

Muonic hydrogen atoms have for a long time been recognized as the ideal tool to study nuclear properties such as charge radii, (magnetic) Zemach radii, or nuclear polarizabilities. Our laser spectroscopy measurements of the Lamb shift in light muonic atoms (H, D, He-3 and He-4) have yielded charge radii...
Theory of hyperfine splitting in muonium and perspectives of its improvement will be reviewed. Emphasis will be on the controversial estimate accuracy of the theoretical prediction. Comparison between theory and the existing and future experimental data will be discussed.
The main goal of the FAMU experiment is to measure for the first time the hyperfine
splitting of the muonic hydrogen ground state and, through this measurement, to determine the proton Zemach radius. To achieve this result, it is necessary to characterize first the muon transfer mechanism from muonic hydrogen to higher-Z elements. This study has been carried on by the FAMU collaboration at...
