利用可调谐窄带宽真空紫外激光系统测量了接近电离极限的氪原子自电离里德堡态。本文观察和分析了的高奇宇称自电离里德堡态的超精细结构。测量和多通道量子亏损理论分析提供了核自旋在光电离中的作用和态的超精细结构的信息。所有天然存在的Kr同位素的电离能测定具有很高的精度和准确度，提高了现有文献的同位素平均电离能值超过一个数量级。
The autoionizing Rydberg states of krypton close to theionization limit were measured using a tunable narrow-bandwidth vacuum-ultraviolet laser system. The hyperfine structure of the high odd-parity autoionizing Rydberg states ofwas observed and analyzed. The measurements and their analysis by multichannel quantum defect theory provided information on the role of the nuclear spin in the photoionization ofand on the hyperfine structure of thestate of. Theionization energies of all naturally occurring Kr isotopes were determined with great precision and accuracy, improving the existing literature values of the isotope-averaged ionization energy by more than one order of magnitude.
