Abstract:
Considering the solar neutrino flux data during the period from June 1989 to April 1992 from four solar neutrino experiments (Cl Solar neutrino experiment, SAGE I & II, GALLEX, Kamiokande II & III) we suggest that the solar neutrino flux appears to be varying with the solar activity cycle. The above variation of solar neutrino flux data with the solar activity cycle and the common periodicity around 2.5 years of solar neutrino flux data, solar diameter data, sunspot number data, solar proton events data, Forbush decreases with solar flares data etc., suggests that the pulsating character of the nuclear energy generation inside the solar core may be their common origin.
