氮原子低激发态的饱和光谱：实验与理论的协调
Saturation spectra of low lying states of Nitrogen: reconciling experiment with theory
摘要：
计算了Jennerich等[Eur. J. D 40（2006）81]从通过近红外饱和光谱记录的跃迁2 p2（3 P）3s 4P_J -2 p2（3 P）3 p 4Po_J'和2 p2（3 P）3s 4P_J -2 p2（3 P）3 p 4Do_J'的观察到的超精细结构，强烈地与Jönsson等人[J. Phys. B：At.摩尔43（2010）115006]。我们对记录到的弱谱线提出了新的解释。如果后者确实被重新解释为交叉信号，推导出一组新的实验超精细常数，与从头算预测非常吻合。
英文摘要：
The hyperfine constants of the levels 2p2(3P)3s 4P_J, 2p2(3P)3p 4Po_J and 2p2(3P)3p 4Do_J, deduced by Jennerich et al. [Eur. Phys. J. D 40 (2006) 81] from the observed hyperfine structures of the transitions 2p2(3P)3s 4P_J - 2p2(3P)3p 4Po_J' and 2p2(3P)3s 4P_J - 2p2(3P)3p 4Do_J' recorded by saturation spectroscopy in the near-infrared, strongly disagree with the ab initio values of Jönsson et al. [J. Phys. B: At. Mol. Opt. Phys. 43 (2010) 115006]. We propose a new interpretation of the recorded weak spectral lines. If the latter are indeed reinterpreted as crossover signals, a new set of experimental hyperfine constants is deduced, in very good agreement with the ab initio predictions.
