摘要
通过光泵磁共振实验设计,对水平场、扫场信号、地磁场不同组合情况下的光泵磁共振信号进行了观测和记录,利用线性拟合的方法测算出铷原子的因子,测算误差只有0.24%;采用固定射频测地磁场的实验方法测得重庆地区的地磁场为0.391 8GS。该应用实验成果丰富了创新性、实用性实验教学内容。
Through the experimental design of optical pumping magnetic resonance, under different combination conditions of horizontal field, sweeping field, and the geomagnetic field, the optical pumping magnetic resonance signal was observed and recorded. By using the linear fitting, we calculate the factor of rubidium atoms,and the measurement error is only 0. 24% ;then under a fixed radio frequen- cy, we measure that geomagnetic field of Chongqing region is 0. 3918 GS. The application of the experiment has an innovative,practical value in teaching content.
