Comparison of the electron and positron anomalous magnetic moments: Experiment 1987
The anomalous magnetic moments of relativistic electrons and positrons have been compared by measuring the spin precession phase difference at a given time interval. The difference in the anomalous magnetic moments between the electron and the positron has been shown to lie within 1×10-8 at 95% confidence level, which improves the accuracy of the previous measurements by an order of magnitude. © 1987.
