利用时域原子干涉仪，在不考虑动力学相移的情况下，测定了旋转磁场部分周期下，g因子为正或负的原子态的Berry相位。实验相移与Berry部分循环相位的预测吻合得很好。结果发现，贝瑞相位的意义取决于磁量子数的符号，旋转磁场的意义，以及状态的g因子的符号。
Berry's phase of the atom in the state with a positive or negative $g$ factor for partial cycles of a rotating magnetic field was determined free from the dynamical phase shift using a time-domain atom interferometer. The experimental phase shift is in good agreement with the prediction of Berry's phase for partial cycles. It was found that the sense of Berry's phase depends on the sign of the magnetic quantum number, the sense of the rotating magnetic field, and the sign of the $g$ factor of the state.
