本文详细介绍了由萨德伯里中微子天文台（SNO）获得的385.17天的第三阶段数据集的太阳中微子分析。在重水靶中安装了一个He-3正比计数器阵列，以精确测量中微子-氘核中性流相互作用的速率。这种测定活动B-8太阳中微子总通量的技术在很大程度上独立于前几个阶段所采用的方法。活动中微子的总通量测量为5.54（-0.31）（+0.33）（stat.）（-0.34）（+0.36）（系统）x 10（6）cm（-2）s（-1），与以前的测量和标准太阳模型一致。对太阳和反应堆中微子混合参数的全球分析得出了最佳拟合值Δ m（2）= 7.59（-0.21）（+0.19）x 10（-5）eV（2）和θ = 34.4（-1.2）（+1.3）度。DOI：10.1103/PhysRevC.87.015502
This paper details the solar neutrino analysis of the 385.17-day phase-III data set acquired by the Sudbury Neutrino Observatory (SNO). An array of He-3 proportional counters was installed in the heavy-water target to measure precisely the rate of neutrino-deuteron neutral-current interactions. This technique to determine the total active B-8 solar neutrino flux was largely independent of the methods employed in previous phases. The total flux of active neutrinos was measured to be 5.54(-0.31)(+0.33)(stat.)(-0.34)(+0.36)(syst.) x 10(6) cm(-2) s(-1), consistent with previous measurements and standard solar models. A global analysis of solar and reactor neutrino mixing parameters yielded the best-fit values of Delta m(2) = 7.59(-0.21)(+0.19) x 10(-5) eV(2) and theta = 34.4(-1.2)(+1.3) degrees.
