Precise laser spectroscopy of the antiprotonic helium atom and CPT test on antiproton mass and charge
H. Yamaguchi, J. Eades, R. S. Hayano +8
We have measured twelve transition frequencies of the antiprotonic helium atom (pbar-He+) with precisions of 0.1--0.2 ppm using a laser spectroscopic method. The agreement between…

Hyperfine Structure Measurements of Antiprotonic Helium and Antihydrogen
E. Widmann, J. Eades, R. S. Hayano +8
This paper describes measurements of the hyperfine structure of two antiprotonic atoms that are planned at the Antiproton Decelerator (AD) at CERN. The first part deals with antipr…
