多电荷离子Au ~（24+）对电子的量子混沌、统计平衡和共振辐射俘获
Quantum chaos, statistical equilibrium and resonant radiative capture of electrons by multicharged ions: Au 24+
摘要：
我们发现，开壳层多电荷原子离子的电离阈值附近的光谱和本征态是混乱的，由于极高的水平密度的多激发电子态（1000级每eV的Au 24+）和一个强大的配置混合。这种复杂性使人们能够使用统计方法来分析系统。轨道占据数服从费米-狄拉克分布，可以引入温度。我们表明，通过多电子共振态的电子的辐射捕获强烈增强相比，直接辐射复合。
英文摘要：
We show that the spectrum and eigenstates of open-shell multicharged atomic ions near the ionization threshold are chaotic, as a result of extremely high level densities of multiply excited electron states (1000 levels per eV in Au 24+) and a strong configuration mixing. This complexity enables one to use statistical methods to analyze the system. The orbital occupation numbers obey the Fermi-Dirac distribution, and temperature can be introduced. We show that radiative capture of electrons through the multielectron resonant states is strongly enhanced compared to the direct radiative recombination.
