Abstract: (APS)
A new double Penning trap structure has been built which permits one to trap a positron in a well-compensated experiment trap where measurements have yielded the geonium positron g-factor anomaly, g(e+)2−1≡a(e+)=(1159652222±50)×10−12. The uncertainty is based on the resonance linewidths and an estimate of the remaining systematic error associated with extrapolating to zero spin-flip power. By comparison to the electron-spin anomaly, a positron/electron g-factor ratio of 1 + (22±64)×10−12 is obtained.- ELECTRON: MAGNETIC MOMENT
