| Abstract: |
Time variations of solar neutrino flux are investigated on the basis of available Homestake experimental data for more than two solar cycles (1970-1994). At first, we determine (with the weight-time function by taking into account [sup 37]Ar decay), for each solar neutrino run n, the effective Earth's heliolatitude L[sub eff](n), the effective Zurich sunspots number Z[sub eff](n), the effective latitude of sunspots distribution Λ[sub eff](n), and the effective surfaces of sunspots in different heliolatitude belts. Then, we consider the correlation of solar-electron-neutrino fluxes with these parameters for different periods of solar activity. It is found that correlation coefficients change sign in different periods of solar activity, so that for total period 1970-1994 the correlation coefficient is very small. The obtained information indicates that a neutrino should have nonzero mass and nonzero magnetic moment. [ABSTRACT FROM AUTHOR] |
