Multiple ionization of Xe-comparison of de-excitation pathways following 3d5/2 ionization and 3d5/2 → 6p resonance excitation

The partial ion yield spectra of Xen+ ions (n = 1-8) were detected by an ion time-of-flight mass analyser in the photon energy range of 664-694 eV, and the branching ratios of ions following the 3d(5/2)(-1) ionization and the 3d(5/2) -> 6p resonance excitation were obtained. The branching ratios were found to be almost the same. Theoretical de-excitation pathways and branching ratios of ions following the 3d(5/2) -> 6p resonance excitation were obtained using the single-configuration approximation and a semi-empirical model, and results were compared with the experiments and the previously published calculations for the 3d(-1) ionization.
