通过使用主动核自旋微波激射器精确测量自旋进动频率,对反磁性原子 129Xe 中电偶极矩的实验研究正在进行中。 A3He 共磁强计已被纳入主动自旋微波激射系统中,以消除外部磁场的长期漂移。此外,还采用了双电池几何结构,以抑制由于与极化 Rb 原子相互作用而产生的频移。首次使用 129Xe 主动自旋微波激射器和 3He 余磁仪进行 EDM 测量。
An experimental search for an electric dipole moment in the diamagnetic atom129Xe is in progress through the precision measurement of spin precession frequency using an active nuclear spin maser. A3He comagnetometer has been incorporated into the active spin maser system in order to cancel out the long-term drifts in the external magnetic field. Also, a double-cell geometry has been adopted in order to suppress the frequency shifts due to interaction with polarized Rb atoms. The first EDM measurement with the129Xe active spin maser and the3He comagnetometer has been conducted.
