Descripción
Sumario:The anomalous magnetic moment a identical to /sup 1///sub 2/ (g-2) of the muon has been measured in the CERN muon storage ring. The result is (116616+or-31).10/sup -8/ compared with the theoretical value (116588+or-2).10/sup -8/ showing agreement to (240+or-270) parts per million. The lifetime of muons moving in a circular orbit with gamma =12 was found to agree with the time dilation predicted by special relativity to within 1.1%. Details are given of the storage ring magnet, the instrumentation and the data analysis. The theoretical implications of the result are discussed. (37 refs).
