%X 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^-14 N, 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.
