Determination of the antiproton-to-electron mass ratio by precision laser spectroscopy of $\overline{p}He^{+}$

A femtosecond optical frequency comb and continuous-wave pulse- amplified laser were used to measure 12 transition frequencies of antiprotonic helium to fractional precisions of (9-16) 10/sup -9lifetimes hitherto unaccessible to our precision laser spectroscopy method. Comparisons with three-body QE...
