利用激光光泵浦，测定了带有烷烃防松弛涂层的蒸汽电池中{sup 85}Rb和{sup 87}Rb原子基态超精细组分之间的微波跃迁的宽度和频移。结果与非线性磁光旋转（NMOR）实验中获得的塞曼弛豫数据进行了比较，这对定量理解涂层细胞的自旋弛豫机制具有重要意义。通过比较四十年来制造的电池，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重要特性。
Using laser optical pumping, widths and frequency shifts are determined for microwave transitions between ground-state hyperfine components of {sup 85}Rb and {sup 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.
