We report on the performance of noble gases for atomic lithium (Li) spectroscopy in the glass vapor cells. The frequency shift and broadening in hyperfine splitting, and their dependence on temperature and density of noble gas were measured by dark resonance in coherent population trapping of ground-state Li atoms.Given a large helium permeation of borosilicate glass, neon gas having a low impact on atomic coherence and low permeation is identified as the best buffer gas among the noble gases

玻璃蒸气电池中锂原子光谱的惰性气体性能

我们报告了惰性气体在玻璃蒸气电池中的原子锂 (Li) 光谱的性能。超精细分裂中的频移和展宽，以及它们对温度和惰性气体密度的依赖性，通过基态锂原子相干布居俘获中的暗共振测量。鉴于硼硅玻璃的大量氦渗透，氖气具有低影响原子相干性和低渗透性被认为是惰性气体中最好的缓冲气体
