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…

Microwave spectroscopic study of the hyperfine structure of antiprotonic helium-3
Susanne Friedreich, Daniel Barna, Fritz Caspers +11
In this work we describe the latest results for the measurements of the hyperfine structure of antiprotonic helium-3. Two out of four measurable super-super-hyperfine SSHF transiti…
