论文摘要
我们使用固定的扭转平衡探测器和一个旋转的吸引子，其中含有18倍和120倍的方位型对称性，同时测试了两个不同长度尺度的$ 1/r^2 $法律。我们以$ 52〜μm和3.0毫米的价格在检测器吸引者的分离中获取数据。牛顿的重力非常适合我们的数据，以95 \％的置信度限制了任何重力 - 强度Yukawa的相互作用，范围$ <38.6〜μ $ m。
We tested the gravitational $1/r^2$ law using a stationary torsion-balance detector and a rotating attractor containing test bodies with both 18-fold and 120-fold azimuthal symmetries that simultaneously tests the $1/r^2$ law at two different length scales. We took data at detector-attractor separations between $52~μ$m and 3.0 mm. Newtonian gravity gave an excellent fit to our data, limiting with 95\% confidence any gravitational-strength Yukawa interactions to ranges $< 38.6~μ$m.
