The Auger decay for the many-electron Xe⁺ (4) state is studied in detail, using multistep approaches. It is found that the single Auger decay channels are primarily Coster–Kronig processes, which is in accord with other theoretical and experimental results. The double and triple Auger decays result primarily from cascade processes, i.e., the sequential two-step and three-step Auger decay, and as such, the contributions from direct processes can be neglected. Level-to-level rates for single, double, and triple decays are obtained, based on which comprehensive Auger electron spectra and ion yields are obtained. Our decay paths and Auger electron spectra are in agreement with the experimental analysis [Hikosaka et al., Phys. Rev. A 76 (2007) 032708], and our ion yield ratios (Xe²⁺: Xe³⁺: Xe⁴⁺ = 4.6 : 87.0 : 8.4) are also in line with their values (5.0 : 86.0 : 9.0). However, with respect to the ion yield ratios, a discrepancy still remains among the experimental and theoretical results. Taking into account the complexity of Xe’s electronic structure, further, more detailed experiments are still required.

使用多步方法详细研究了多电子 Xe ⁺ (4 ) 态的俄歇衰变。发现单个俄歇衰变通道主要是Coster-Kronig过程，这与其他理论和实验结果是一致的。二次和三次俄歇衰变主要来自级联过程，即连续的两步和三步俄歇衰变，因此直接过程的贡献可以忽略不计。获得了单、双和三衰变的水平到水平速率，在此基础上获得了全面的俄歇电子光谱和离子产率。我们的衰变路径和俄歇电子光谱与实验分析一致[Hikosaka et al。, 物理。Rev. A 76 (2007) 032708]，我们的离子产率比（Xe ²⁺ : Xe ³⁺ : Xe ⁴⁺ = 4.6 : 87.0 : 8.4）也符合它们的值（5.0 : 86.0 : 9.0）。然而，关于离子产率比，实验和理论结果之间仍然存在差异。考虑到Xe电子结构的复杂性，还需要更详细的实验。
