光磁共振实验测量g_F值方法的改进与拓展

Improvement and expansion of the method for measuring g_F in optical pumping magnetic resonance experiment

分析了光磁共振实验测量 gF 值中传统方法存在的问题 ,提出了利用光抽运信号的变化来判断合磁场方向的改进措施 ,避免了实验过程中对合磁场的方向和大小的误判以及光抽运信号与共振信号的混杂 .同时 ,拓展了原有的测量方法 。

The problems of measuring g F in optical pumping magnetic resonance experiment are analyzed, and the improved measures are presented, by which the direction of the join magnetic field can be judged from the variation of optical pumping signal. The misjudgement of the direction of join magnetic field and the mixture of optical pumping signals and magnetic resonance signals are all avoided. Meanwhile, the general measuring method is expanded, and the content of experiment is enriched.
