摘要
本文讨论了在光泵磁共振实验中,地磁场垂直分量的抵消、样品泡所在处恒定磁场的确定和实验中的干扰信号等问题。阐明了地磁场垂直分量不被抵消情况下,对实验结果的影响;在实验中采用利用一种元素测量样品所在处磁场的方法,准确确定样品泡所在处的恒定磁场;最后对实验中的干扰信号进行了分析。
We discuss some problems in optical pumping magnetic resonance experiment： the balance of vertlca/part of the geomagnetlsm,the exact value of magnetic field where the sample locates and the disturbing signals. Our results show the effect to the experiment when we don＇t balance the geomagnetism. We find that the exact value of magnetic field can be calculated by using the data measured from one of the two elements. We also analyzed the disturbing signals.
