Abstract： A torsion pendulum containing two sapphire crystals and two lead rings is used to test Weber’s theory of enhanced solar neutrino coherent scattering. Our experiment gives a null result for the diurnal force with a noise level of 3.8×10-14N, which is 526 times smaller than the predicted value of Weber’s theory, and directly rules out Weber’s theory and the experimental result. This experiment also reveals a test of the weak equivalence principle with η (Al2O3, Pb) = (0.8±3.1) × 10-10 for masses falling toward the Sun.
