Abstract
Photon-induced fluorescence spectroscopy was applied to measure absolute fluorescence emission cross sections from the main 5s- and first satellite levels of Xe II upon photoionization from Xe I in a broad exciting-photon energy range (23-28eV) with 20meV bandwidth of the exciting radiation and in a narrow energy range (23.25-23.50eV) with a bandwidth of 1.8meV. The average fluorescence resolution amounted to 0.07nm. Fluorescence emission cross sections were computed with taking into account many-electron correlations and doubly excited states. Computed cross sections, especially in integrated form, agree well with the results of experiment. Many features observed in the high resolution experiment are identified to originate from nf-Rydberg series.
