It is shown that the rate of formation of 37Ar in the Brookhaven solar-neutrino detector oscillates with periods 20 ±1, 25.5 ±1.5 months, and —11 years and with a modulation depth £0.3 with a confidence level not lower than 99.5%. These oscillations are interpreted as resulting from the modulation of the neutrino flux by gravitational oscillations at the center of the sun. Further experiments for studying the sun's neutrino brightness curve with the help of the chlorine-argon neutrino detector are discussed.
