Abstract
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 [superscript 3]He 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 [superscript 8]B 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[subscript −0.31][superscript +0.33](stat.)[subscript −0.34][superscript +0.36](syst.)×10[superscript 6] cm[superscript −2] s[superscript −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 Δm[superscript 2]=7.59[subscript −0.21][superscript +0.19]×10[superscript −5] eV[superscript 2] and θ=34.4[subscript −1.2][superscript +1.3] degrees.
