Abstract

Revisited study of the EΣ (6S)←AΠ(5P) transition in CdAr using both theoretical and experimental approach is presented. Systematic detection of the EΣ,υ'←AΠ,υ″=6 transition frequencies with higher accuracy and spectrally narrower laser extended and improved analysis and simulation of the LIF excitation spectrum. More consistent characterization of the EΣ-Rydberg state inner well using inversed perturbation approach methodology was achieved. Free←bound transitions in the EΣ←AΠ,υ″=6 excitation were taken into account in the analysis and simulation of the recorded spectrum. The updated spectroscopic characterization of the AΠ state was also revisited.

摘要

本文介绍了使用理论和实验方法对CdAr中EΣ(6S)←AΠ(5P)跃迁进行的重新研究。通过系统地检测EΣ,υ'←AΠ,υ″ = 6跃迁频率，以更高的精度和更窄的光谱线宽扩展并改进了激光诱导荧光（LIF）激发光谱的分析和模拟。使用逆微扰方法对EΣ-里德堡态内阱进行了更一致的表征。在记录光谱的分析和模拟中考虑了EΣ←AΠ,υ″ = 6激发中的自由-束缚跃迁。还重新审视了AΠ态的更新光谱表征。
