Systematic study of the decay rates of antiprotonic helium states
H. Yamaguchi, R. S. Hayano, T. Ishikawa +8
A systematic study of the decay rates of antiprotonic helium (\pbhef and \pbhet) at CERN AD (Antiproton Decelerator) has been made by a laser spectroscopic method. The decay rates…

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…
