  A precise measurement of the anomalous g value, a_mu=(g-2)/2, for the
positive muon has been made at the Brookhaven Alternating Gradient Synchrotron.
The result a_mu^+=11 659 202(14)(6) X 10^{-10} (1.3 ppm) is in good agreement
with previous measurements and has an error one third that of the combined
previous data. The current theoretical value from the standard model is
a_mu(SM)=11 659 159.6(6.7) X 10^{-10} (0.57 ppm) and a_mu(exp)-a_mu(SM)=43(16)
X 10^{-10} in which a_mu(exp) is the world average experimental value.
