Abstract: 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.

Key words: optical pump magnetic resonance, optical pumping, amplitude of sweep field, transition rate
