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…
