Abstract

Measurements with a one-electron quantum cyclotron determine the electron magnetic moment, given by g/2=1.00115965218073(28)[0.28 ppt]g/2 = 1.001\,159\,652\,180\,73\,(28)\,[0.28~\textrm{ppt}], and the fine structure constant, α1=137.035999084(51)[0.37 ppb]\alpha^{-1}=137.035\,999\,084\,(51)\,[0.37~\textrm{ppb}]. Brief announcements of these measurements are supplemented here with a more complete description of the one-electron quantum cyclotron and the new measurement methods, a discussion of the cavity control of the radiation field, a summary of the analysis of the measurements, and a fuller discussion of the uncertainties.
