Direct Observation of the Hyperfine Transition of the Ground State Positronium
T. Yamazaki, A. Miyazaki, T. Suehara +7
We report the first direct measurement of the hyperfine transition of the ground state positronium. The hyperfine structure between ortho-positronium and para-positronium is about…
First direct measurement of positronium hyperfine splitting with sub-THz light
T. Yamazaki, A. Miyazaki, T. Suehara +8
Positronium is an ideal system for the research of the bound state QED. The hyperfine splitting of positronium (Ps-HFS, about 203 GHz) is an important observable but all previous m…
Detection of the Direct Hyperfine Transition of Positronium Atoms using sub-THz High-power Radiation
T. Suehara, A. Miyazaki, T. Yamazaki +11
Hyperfine splitting of positronium is an important parameter for particle physics. This paper gives experimental techniques and results of R&D studies of our experiment to observe…
Precise measurement of Hyper Fine Structure of positronium using sub-THz light
S. Asai, T. Suehara, T. Yamazaki +9
Positronium is an ideal system for the research of the QED, especially for the QED in bound state. The discrepancy of 3.9σis found recently between the measured HFS values and the…
