我们将所谓的超冷中子重力增强去极化的预期效果与暴露于各种垂直磁场梯度的自旋进动室中进行的测量进行了比较。特别是，我们研究了自旋去极化率以及测量的中子拉莫尔进动频率的变化对这些场梯度的依赖性。我们发现了极好的定性一致性，重力增强的去极化解释了数据中一些先前无法解释的特征。
We compare the expected effects of so-called gravitationally enhanced depolarization of ultracold neutrons to measurements carried out in a spin-precession chamber exposed to a variety of vertical magnetic-field gradients. In particular, we have investigated the dependence upon these field gradients of spin-depolarization rates and also of shifts in the measured neutron Larmor precession frequency. We find excellent qualitative agreement, with gravitationally enhanced depolarization accounting for several previously unexplained features in the data.
