摘要:

利用激光抽运,测定了具有烷烃反弛豫膜的汽室中$^{85}$ Rb和$^{87}$ Rb原子基态超精细组分之间的微波跃迁宽度和频移.结果进行了比较与塞曼弛豫的非线性磁光旋转(NMOR)实验中获得的数据,比较重要的定量理解的自旋弛豫机制在涂层细胞。通过比较四十年来生产的电池,我们证明了涂层电池的长期稳定性,这是原子钟和磁力计的一个重要特性。

英文摘要:

Using laser optical pumping, widths and frequency shifts are determined for microwave transitions between ground-state hyperfine components of $^{85}$Rb and $^{87}$Rb atoms contained in vapor cells with alkane anti-relaxation coatings. The results are compared with data on Zeeman relaxation obtained in nonlinear magneto-optical rotation (NMOR) experiments, a comparison important for quantitative understanding of spin-relaxation mechanisms in coated cells. By comparing cells manufactured over a forty-year period we demonstrate the long-term stability of coated cells, an important property for atomic clocks and magnetometers.
