Super-Kamiokande-I Rate Time Variation Data

Angular Distribution of Solar Neutrino Event Candidates in Super-Kamiokande-I. 

The angular deviation between the solar and the reconstructed direction of events with total energies ranging between 5 and 20 MeV is shown. From the strong forward peak due to elastic scattering of solar ^8B neutrinos with electrons 22,400+-200(stat) solar neutrino interactions were observed in 22,500 metric tons of water during 1496 live days.

The observed solar neutrino interaction rate is 0.465+-0.005(stat.)+0.016-0.015(sys.) of the rate expected by the standard solar model (SSM). Assuming only solar nu_e the observed rate corresponds to a ^8B flux of 2.35+-0.02(stat.)+-0.08(sys.)x10^6/cm2/s.



All uncertainties given for the time variation data are only statistical and based on an asymmetric Gaussian approximation of the underlying likelihood functions obtained by an unbinned maximum likelihood fit to the cos(theta_sun) distributions.

The top two panels show the Super-Kamiokande-I rate as a function of time. The topmost panel uses bins of 10 days width, the middle panel displays 45 day bins. The lower left panel combines the 10-day bins into 12 bins to show the yearly cycle assuming asymmetric Gaussians for the probability density functions. The lower right panel shows the yearly variation data in 8 bins obtained from a similar combination of the 45-day data bins. The middle right panel is the yearly variation data in those same 8 bins, but resulting directly from a maximum likelihood fit to the cos(theta_sun) distribution.

The table below gives the flux (assuming a pure nu_e solar neutrino flux) inferred from the measured elastic scattering rate in each data bin.
