摘要
通过分析光泵磁共振过程中的原子辐射跃迁过程和跃迁速率,建立了光泵磁共振过程的理论模型,推导得出了光泵磁共振信号幅度与扫场的关系式,并与实验结果进行了比较.理论计算与实验结果符合较好,本实验对深入理解光泵磁共振过程具有重要意义.
A theoretical model about the process of optical pump magnetic resonance resonance has been established by analyzing the atomic radiative transition process and transition rate. On the basis ,the relationship between signal amplitude of optical pump magnetic resonance and the amplitude of sweep field has been derived and compared with the experimental results. It is found that theoretical calculation is in agreement well with the experimental results, thus,the experiment is of great significance on the deep understanding of the optical pump magnetic resonance process.
