[Variations in the intensity of solar neutrinos as a problem for physical chemistry]

A comparison of variations in the solar neutrino flux in Brookhaven measurements with solar activity indices clearly shows that the neutrino flux is controlled by surface solar processes. These processes can lead to changes in the efficiency of registrations of the neutrino flux. From this view point, the results of the measurements of the neutrino flux on the Brookhaven detector in 1970-1994 (108 runs) were analyzed. It was found that the neutrino flux depends on the heliogeophysical situation. The well known anticorrelation between the neutrino flux and Wolf numbers is observed only for odd cycle of solar activity. A similar regularity occurs for critical frequencies of E-ionosphere. By contrast, the correlation between the neutrino flux and the Ap-index is observed only for the even activity cycle. The predominance of the sign of radial component of the interplanetary magnetic field in the last 7-14 days of exposure has the greatest effect on the neutrino flux (this sign changes as the sign of the total magnetic field of the Sun changes). In short runs, the neutrino flux changes more than threefold. The conclusion is made that variations of the solar neutrino flux are falcious. These fictitious variations are caused probably by the action of very low-frequency electromagnetic emissions of the magnetosphere upon the substance of the target and the technology of the extraction of 37Ar atoms from perchloretylene.
