摘要：

Fourier analysis of the R. Davis group data has been carried out. A method of signal selection at small signal/noise ratio was suggested and significance levels of individual peaks in the spectrum were determined. The correlation coefficients of neutrino fluxes and some characteristics of solar activity were calculated. The analysis conducted allowed us to reveal three significant peaks in the spectral density of Ar-37 production rate in Cl detector: 113.8, 55.6, and 26.6 months (with a ratio of approximately 4:2:1). The probability of a random origin of these peaks is less than 4%.
