  A higher precision measurement of the anomalous g value, a_mu = (g-2)/2, for
the positive muon has been made at the Brookhaven Alternating Gradient
Synchrotron, based on data collected in the year 2000. The result a_{mu^+} = 11
659 204(7)(5) times 10^{-10} (0.7 ppm) is in good agreement with previous
measurements and has an error about one half that of the combined previous
data. The present world average experimental value is a_mu(exp) = 11 659 203(8)
times 10^{-10} (0.7 ppm).
