论文摘要
我们根据$^{129} $ Xe的旋转预申请和$^{131} $ Xe原子在玻璃单元中的旋转预申请研究原子comagnetometer设计。 $^{131} $ Xe的进型光谱中的四极分裂已完全解决，从而可以精确地确定磁性旋转进液频率。由于细胞的几何形状和表面特性，其特征在于以非零的不对称参数$η$的特征，因此修改了四极杆分离对细胞轴和偏置磁场之间的相对方向的依赖性，并导致$^$^$^^131，这会导致四极杆对相对方向的依赖，并导致$^131的额外校正。我们在理论上还是在实验上检查了这些效果，并开发了量化和控制此类转移的方法。
We study an atomic comagnetometer design based on the spin precessions of $^{129}$Xe and $^{131}$Xe atoms in glass cells. The quadrupole splittings in the precession spectrum of $^{131}$Xe are fully resolved, allowing a precise determination of the magnetic-dipole precession frequency. The transverse asymmetry of quadrupole interactions, due to both the geometry and surface properties of the cell, characterized by a non-zero asymmetry parameter $η$, modifies the dependence of the quadrupole splittings on the relative orientation between the cell axes and the bias magnetic field, and lead to additional corrections in the precession frequencies of $^{131}$Xe atoms. We examine these effects both theoretically and experimentally, and develop methods to quantify and control such shifts.
