摘要：The Muon (g-2) Experiment (E821) at Brookhaven National Laboratory
(BNL) started data taking in 1997. The latest result a+ = 11659202(14)(6) 10−10,
based on statistics of about 1 billion decays collected in 1999, is in good agreement with
the previous measurement. With the precision of 1.3 ppm, the result, compared with
the Standard Model evaluation a(SM) = 11659159:6(6:7)10−10, shows a di
erence of
a(exp) − a(SM) = 43(16) 10−10.
