Measurement of the hyperfine structure of antiprotonic helium
This paper discusses the level splitting of the antiprotonic helium atomcule, an exotic atom consisting of a helium nucleus, an electron, and an antiproton which occupies highly excited states with angular momentum of L $9 approximately=30-35. The observation of a splitting in a laser transition bet...
