摘要
We have carried out a high precision torsion balance experiment in searching for abnormally large coherent scattering cross sections between a sapphire crystal and solar-neutrino.According to the hypothesis and the experimental results presented by J.Weber,a diurnal effect,which was 60 times larger than the noise level,should he observed obviously,but no significant diurnal effects were found at the level of 8.1 x 10^(-8) dyn in our experiment.
