摘要：

The yield spectra of Xe2+ and Xe3+ ions near the 4d ionization limits have been measured by a threshold electron-photoion coincidence method. These spectra consist of some prominent peaks corresponding to the 4d-1np Rydberg states and two dominant peaks corresponding to 4d threshold ionization. It is proposed that threshold-electron emission from the inner-shell resonance states is due to not only shake-off (e.g. Xe 4d(-1)6p --> Xe2+ 5p-2) but also two-step autoionization (e.g. Xe 4d(-1)6p --> Xe+ 5s(-1)5p(-1)7p --> Xe2+ 5s(-1)5p-1). The two-step autoionization process plays an important role in decays from the lower n Rydberg states. Two dominant peaks somewhat above the 4d ionization limits show the effect of post-collision interaction, namely, shifts of peak positions and asymmetric profiles. The shifts are almost the same in the Xe2+ and Xe3+ spectra.
