标题： Gravitational Couplings of Intrinsic Spin

摘要： 引力自旋耦合被简要回顾。 在旋转质量的外部引力场中，狄拉克方程的一个结果被详细考虑，即在旋转物体表面附近，自旋为1/2的粒子垂直向上和向下的能量差异是$\hbar\Omega\sin\theta$。 这里$\theta$是纬度， $\Omega = 2GJ/(c^2 R^3)$，其中$J$和$R$分别是物体的角动量和半径。 似乎这种相对论量子引力效应在未来可预见的时期内是可以测量的。 显示英文摘要

摘要： The gravitational couplings of intrinsic spin are briefly reviewed. A consequence of the Dirac equation in the exterior gravitational field of a rotating mass is considered in detail, namely, the difference in the energy of a spin-1/2 particle polarized vertically up and down near the surface of a rotating body is $\hbar\Omega\sin\theta$. Here $\theta$ is the latitude and $\Omega = 2GJ/(c^2 R^3)$, where $J$ and $R$ are, respectively, the angular momentum and radius of the body. It seems that this relativistic quantum gravitational effect could be measurable in the foreseeable future.
