摘要
The recent results from the solar neutrino observation in Super-Kamiokande is presented. From the 504 days of data, taken between the 31st of May, 1996 and the 25th of March, 1998, we have obtained the B-8-solar neutrino flux ratio to the prediction of the standard solar model of BP98 to be 0.474(-0.009)(+0.010) (+0.017)(-0.014) (0.506(-0.010)(+0.011) (+0.018)(-0.015) for TC98). We found no significant difference between day and nighttime flux. The spectrum shape is compared with the expected from the B-8-neutrino spectrum, the neutrino interaction and the detector response, and we have obtained chi(2) Of 25.3 (15 d.o.f), corresponding to a 4.6% C.L. Implications of these measurements to neutrino oscillations are discussed.
