使用萨德伯里中微子天文台在 4 年时间间隔内收集的数据，对 8B 太阳中微子通量的正弦周期性变化进行了搜索。 1年周期的变化与地球轨道偏心率对8B中微子通量的调制一致。通过未分箱最大似然分析或 Lomb-Scargle 周期图分析，未发现 1 d 至 10 年周期的显着正弦周期性。这些数据与 Sturrock 等人基于 Super-Kamiokande 中的弹性散射事件最近分析的结果可归因于总 8B 中微子通量的 7% 正弦调制的假设不一致。
A search has been made for sinusoidal periodic variations in the 8B solar neutrino flux using data collected by the Sudbury Neutrino Observatory over a 4-year time interval. The variation at a period of 1 yr is consistent with modulation of the 8B neutrino flux by the Earth's orbital eccentricity. No significant sinusoidal periodicities are found with periods between 1 d and 10 years with either an unbinned maximum likelihood analysis or a Lomb-Scargle periodogram analysis. The data are inconsistent with the hypothesis that the results of the recent analysis by Sturrock et al., based on elastic scattering events in Super-Kamiokande, can be attributed to a 7% sinusoidal modulation of the total 8B neutrino flux.
