光泵磁共振实验中测量gF值多种方法的探讨

光泵磁共振法是用光抽运方法和光探测法对弱磁场信号进行检测。恒定水平磁场换向测gF值，恒定频率换向测gF值，以及由最小二乘法求出直线的斜率计算gF值。阐述了前2种方法下如何区分。87Rb和85Rb出共振谱线。3种方法测量gF值其结果是一致。

Many different methods of measuring the gF value in the experiment of optical pumping magnetic resonance

We can make use of optical pumped and optical detected to carry on examination to the weak magnetic field signal in the magnetic resonance imaging with optical pumping,then the accurate measurement of gF value may be acquired by transfering the direction the level and constant magnetic field. Secondly,the gF value may be worked out by the slope ,if we use the method of least squares to get the quasilinear equation of experiment data . In this test there are the analysis and comparisons to the two kinds of many different methods. The result is consistent in three kinds of methods to measure the gF value.
