外磁场中Rb纳米电池对$D_2$线禁戒跃迁的研究
Study of forbidden atomic transitions on $D_2$ line using Rb nano-cell placed in external magnetic field
摘要：
通过基于Rb纳米单元使用的所谓的$λ$-Zeeman技术的实验探索，我们首次揭示了在100 - 1100 G的范围内的强外部磁场$B$中的$^{87}$ Rb、$D_2$线$F_g=1 \rightarrow F_e=0, 1, 2, 3$原子跃迁的概率的强烈修改，包括禁止的$F_g=1, m_F =0 \rightarrow F_e=1, m_F =0$和$F_g=1, m_F =-1 \rightarrow F_e=3, m_F =-1$跃迁（当$B = 0$时这些是禁止的跃迁）。对于$π$偏振激发二极管激光辐射（$λ= 780$ nm），这些在$B > 150$ G处的禁戒跃迁是在检测到的透射光谱中最强的原子跃迁之一。个别超精细跃迁随磁场的频移也被提出：特别是，$F_g=1, m_F =+1 \rightarrow F_e=1, m_F =+1$原子跃迁具有独特的行为，因为它的频率几乎保持不变，当$B$从100到1100 G变化。所建立的理论模型能很好地描述实验。
英文摘要：
By experimental exploration of the so-called $λ$-Zeeman technique based on Rb nano-cell use we reveal for the first time a strong modification of the probability of the $^{87}$Rb, $D_2$ line $F_g=1 \rightarrow F_e=0, 1, 2, 3$ atomic transitions, including forbidden $F_g=1, m_F =0 \rightarrow F_e=1, m_F =0$ and $F_g=1, m_F =-1 \rightarrow F_e=3, m_F =-1$ transitions (these are forbidden transitions when $B = 0$) in a strong external magnetic field $B$ in the range of 100 - 1100 G. For $π$-polarized exciting diode laser radiation ($λ= 780$ nm) these forbidden transitions at $B > 150$ G are among the strongest atomic transitions in the detected transmission spectra. Frequency shifts of the individual hyperfine transitions versus magnetic field are also presented: particularly, $F_g=1, m_F =+1 \rightarrow F_e=1, m_F =+1$ atomic transition has a unique behavior, since its frequency remains practically unchanged when $B$ varies from 100 to 1100 G. Developed theoretical model well describes the experiment.
