我们对固体 {sup 4}He 基质中分离的 Cs 原子的 6S{sub 1/}2-6P{sub 1/2} 跃迁的吸收和荧光光谱进行了系统的实验研究。早期开发的液氦中碱金属原子的气泡模型经过修改并应用于本系统。通过分析液体和固体 He（立方和六方）环境中吸收和荧光波长对 He 压力的依赖性，我们通过考虑原子泡对固体 He 的弹性变形来修改气泡模型。
We present a systematic experimental study of the absorption and fluorescence spectra of the 6S{sub 1/}2-6P{sub 1/2} transition in Cs atoms isolated in solid {sup 4}He matrices. The bubble model developed earlier for alkali-metal atoms in liquid He is revised and applied to the present system. The analysis of the dependencies of absorption and fluorescence wavelengths on He pressure in liquid and solid He (cubic and hexagonal) environments leads us to modify the bubble model by taking the elastic deformation of solid He by the atomic bubble into account.
