Abstract The Fourier analysis of R.Davis group data has been carried out. A method of a signal selection at small signal/noise ratio was suggested and the 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 conducted analysis allowed to reveal three significant peaks in a spectral density of 37Ar production rate in Cl detector: 113.8, 55.6 and 26.6 monthes (with ratio 4:2:1). The probability of random origin of these peaks is less than 4%.
