摘要:
The 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 by discharging mixture gases of helium and krypton. A total of 121 lines of neutral Krypton have been measured, among them 33 lines have been classified in previous works, 45 lines were newly classified with the known energy levels, and 42 lines cannot be classified with the known energy levels. These unclassified lines indicate new energy levels of Kr must exist. Further, analysis of the unclassified lines to get possible new energy levels with a classification program is reported.
