Abstract
Results from 1036 days of solar neutrino data accumulated in the upgra ded Kamiokande detector (Kamiokande III) are presented. The B-8 solar neutrino flux observed in Kamiokande III is 2.82(-0.24)(+0.25)(stat) /- 0.27(syst) x 10(6) cm(-2) s(-1); the combined flux from Kamiokande II and III (2079 days in total) is 2.80 +/- 0.19 (stat) +/- 0.33 (syst ) x 10(6) cm(-2) s(-1), which is 49% to 64% of the standard solar mode ls. These combined data from January 1987 to February 1995, covering a n entire period of solar cycle 22, enabled us to study a correlation b etween the neutrino flux and the solar activity in detail: no strong c orrelation of the solar neutrino flux with the sunspot numbers was fou nd within experimental errors. The result on a search for the daytime and nighttime flux difference is also reported.
