摘要：
The third and last phase of the Sudbury Neutrino Observatory (SNO) used a technique independent of previous methods, to measure the rate of neutral-current interactions in heavy water and determine precisely the total active B-8 solar neutrino flux. The total flux obtained is 5.54(-0.31)(+0.33)(stat)(-0.34)(+0.36) x 10(6) cm(-2) s(-1), in agreement with previous measurements and standard solar models. Results from a global analysis of solar and reactor neutrino give Delta m(2) = 7.59(-0.21)(+0.19) x 10(-5) eV(2) and theta = 34.4(-1.2)(+1.3) degrees with a reduced uncertainty on the mixing angle compared to previous phases.
