| 摘 要： | 本文利用浓度调制的万法测量了氪原子在11870～12700 cm~(-1)波段的高分辨连续吸收光谱.在实验中,通过对氪气和氦气混合气体进行放电的方法制备氪原子.总共测量了120根氦原子吸收谱线,其中33根谱线是已被报道过的,45根新测量的谱线可以通过已知的氪原子能级进行标定,其它剩下的42根新测量的谱跃迁线根据已知的氪原子能级信息尚无法进行标定.本次实验中的这些未知的42根氪原子的跃迁谱线,可以推断氪原子有尚未被报道或测量过的原子能级存在.本文同时对如何用"Classification"计算软件分析未知氪原子谱线的可能存在的能级进行了演示.

| Abstract: | High-resolution absorption spectra of atomic krypton in the range of 11870-12700 cm?1 were recorded by employing concentration modulation absorption spectroscopy technique with a tunable single-mode cw Ti:Sapphire laser. The krypton atoms were excited to the absorbing energy states by discharge-burning in a mixture of helium and krypton. A total of 120 lines of neutral krypton were observed, among them 33 lines had already been classified in previous studies, 45 lines were newly classi ed with the known energy levels, and 42 lines cannot be classi ed. These unclassified lines indicate that up to now unknown energy levels of Kr must exist. Further, an analysis of the unclassi ed lines to get possible new energy levels with a classi cation program is reported. |
