Description

Antiprotonic helium, a neutral three-body system pe-He2+(=pHe+), produced when antiprotons (p) are captured in various phases of helium, comprises a series of long-lived (∼ μs lifetime) states with large principal and orbital quantum numbers (n,l). In recent experiments at the CERN AD (antiproton decelerator), comparing experimental values with 3-body QED calculations, we deduced that the antiproton and proton charges and masses agree to within 6 x 10-8.
