Abstract

Results from 1036 days of solar neutrino data accumulated in the upgraded Kamiokande detector (Kamiokande III) are presented. The ⁸B solar neutrino flux observed in Kamiokande III is 2.82^+0.25_-0.24 (stat) ± 0.27 (syst) × 10⁶ cm^-2s^-1; the combined flux from Kamiokande II and III (2079 days in total) is 2.80 ± 0.19 (stat) ± 0.33 (syst) × 10⁶ cm^-2s^-1, which is 49% to 64% of the standard solar models. These combined data from January 1987 to February 1995, covering an entire period of solar cycle 22, enabled us to study a correlation between the neutrino flux and the solar activity in detail: no strong correlation of the solar neutrino flux with the sunspot numbers was found within experimental errors. The result on a search for the daytime and nighttime flux difference is also reported.
