摘 要
這篇論文旨在研究Xe原子從5p56p至5p55d於波長3107.77 nm的中紅外躍遷譜線，我們利用原子能階理論以及現有實驗數據，首先估計5p55d的超精細結構係數，並得出此躍遷的Isotope shift，更進一步預測此躍遷的超精細結構。期望能對未來的光譜量測有所助益。
未來我們將利用本實驗發展的DFG (Difference Frequency Generation)光源進行此躍遷的飽和吸收光譜測量。在本篇論文我們完成了實驗前所有的必要準備。首先我們建立一套氣體填充系統，並利用此系統完成了Xe氣體在低氣壓的填充，製作一0.1 mTorr Xe氣室。隨後成功地利用RF放電的方法使Xe氣體放電，並觀察Xe在可見光的光譜，檢驗此氣室的乾淨程度。

This thesis focuses on the Xe mid-IR 5p56p to 5p55d transition spectrum at the wavelength 3107.77 nm. First, we utilize the atomic theory and the available experimental data to estimate the hyperfine structure coefficient and isotope shift among various xenon isotopes. Furthermore, we predict the hyperfine structures in this transition. We expect it can be benefit to our future spectroscopic measurement.
We will utilize our laboratory developed DFG (Difference Frequency Generation) light source to proceed the saturation absorption spectroscopic measurement in the future. In this thesis, we accomplish the necessary preparations before experiment. First, we establish the gas filling in a compact pyrex cell at the low pressure of 0.1 mTorr. After that, we successfully ignite the xenon gas discharge by the use of RF discharge. We also observe the Xe spectrum in the visible wavelength to examine the cleanness of this gas cell.
