摘要：

We rotated a 3 ton U-238 attractor around a compact torsion balance and compared the accelerations of Cu and Pb toward U. We found that a(Cu) - a(Pb) = (-0.7 +/- 5.7) x 10(-13) cm/s(2), compared to the equivalence-principle violating interactions with Yukawa ranges down to 1 cm and rule out an earlier suggestion of a Yukawa interaction coupled predominantly to N - Z.
