Abstract

A new measurement of the positive muon's anomalous magnetic moment has been made at the Brookhaven Alternating Gradient Synchrotron using the direct injection of polarized muons into the superferric storage ring. The angular frequency difference ω_a between the angular spin precession frequency ω_s and the angular orbital frequency ω_c is measured as well as the free proton NMR frequency ω_p. These determine R =ω_a/ω_p=3.707 201(19)×10^-3. With μ_μ/μ_p=3.183 345 39(10) this gives a_μ+=11 659 191(59)×10^-10 (±5 ppm), in good agreement with the previous CERN and BNL measurements for μ⁺ and μ^-, and with the standard model prediction.
