In-beam measurement of the hydrogen hyperfine splitting - towards antihydrogen spectroscopy
M. Diermaier, C. B. Jepsen, B. Kolbinger +6
Antihydrogen, the lightest atom consisting purely of antimatter, is an ideal laboratory to study the CPT symmetry by comparison to hydrogen. With respect to absolute precision, tra…
