Two-photon laser spectroscopy of antiprotonic helium and the antiproton-to-electron mass ratio
Masaki Hori, Anna Sótér, Daniel Barna +9
Physical laws are believed to be invariant under the combined transformations of charge, parity and time reversal (CPT symmetry). This implies that an antimatter particle has exact…

Hyperfine structure of antiprotonic helium revealed by a laser-microwave-laser resonance method
E. Widmann, R. S. Hayano, T. Ishikawa +9
Using a newly developed laser-microwave-laser resonance method, we observed a pair of microwave transitions between hyperfine levels of the state of antiprotonic he…
