Antiproton–to–electron mass ratio determined by two-photon laser spectroscopy of antiprotonic helium atoms
The ASACUSA collaboration of CERN has recently carried out two-photon laser spectroscopy of antiprotonic helium atoms. Three transition frequencies were determined with fractional precisions of 2.3–5 parts in 109. By comparing the results with three-body QED calculations, the antiproton-to-electron...
