Super-Kamiokande-I 中太阳中微子与电子的弹性散射率的时间变化符合主动双中微子振荡的预期变化。大混合角解中的最佳拟合具有 tan^2theta=0.55 的混合角以及两个中微子质量本征态之间的质量平方差 Deltam^2=6.3times10^-5eV^2。拟合的日/夜不对称性 -1.8+-1.6(stat)+1.3-1.2(syst)% 比之前的测量结果提高了统计精度，并且与预期的 -2.1% 不对称性非常吻合。
The time variation of the elastic scattering rate of solar neutrinos with electrons in Super-Kamiokande-I was fit to the variations expected from active two-neutrino oscillations. The best fit in the Large Mixing Angle solution has a mixing angle of tan^2theta=0.55 and a mass squared difference of Deltam^2=6.3times10^-5eV^2 between the two neutrino mass eigenstates. The fitted day/night asymmetry of -1.8+-1.6(stat)+1.3-1.2(syst)% has improved statistical precision over previous measurements and agrees well with the expected asymmetry of -2.1%.
