光泵磁共振实验中实验参数选取的探讨RESEARCH ON EXPERIMENTAL PARAMETERS IN OPTICAL-PUMPING MAGNETIC RESONANCE EXPERIMENTS

摘要(Abstract):
在光泵磁共振实验中,选择合适的射频频率、扫场幅度和外加水平磁场对实验的顺利进行和保证实验测量结果的精度有着重要作用。虽然已有很多文章探讨过相关问题,但并未明确提出关于上述实验参数选取的原则以及相应的参数取值范围。本文提出在光泵磁共振实验中,相关实验参数的选取应该使得在测量过程中能够观测到所有对应于三角波峰和波谷位置的共振信号并明确地区分信号来源。本文通过理论分析给出了不同测量方法下相应的实验参数取值范围,并通过实验测量验证了这些参数取值范围的合理性。
