A heuristic approach to the detection of solar neutrinos

In this paper we consider the coherent scattering of the solar neutrino flux off target matter in a terrestrial detector. We propose a heuristic approach that targets the apparent abnormal neutrinos scattering on high Debye temperature monocrystals. The possibility of observing the diurnal effect of solar neutrinos using the presumed coherent scattering on high Debye temperature monocrystals, such as sapphire, is presented and discussed. A ?Cavendish-type? torsion balance is used for the measurement of the presumed neutrino-induced torques. An effect correlated with the direction of the sun was observed.
