电子与具有开放f壳层的多电荷离子（例如Au 25+和W 20+）的复合由混沌多电子共振主导。它们导致荧光产率在低能量下完全占主导地位，导致复合率提高高达1000倍。在较高的能量下，许多自电离通道的打开导致荧光产率的快速降低。我们应用统计理论来表示的复合截面的总和门口（双电子）共振。
Electron recombination with multicharged ions that have open f shells (e.g. Au25+ and W20+) is dominated by chaotic many-electron resonances. They cause the fluorescence yield to dominate entirely at low energies leading to an enhancement of the recombination rate up to 1000 times. At higher energies the opening of many autoionization channels leads to a rapid decrease of the fluorescence yield. We apply the statistical theory to express the recombination cross section as a sum over the doorway (dielectronic) resonances.
