    "abstract": "We show that the spectrum and eigenstates of open-shell multicharged atomic\nions near the ionization threshold are chaotic, as a result of extremely high\nlevel densities of multiply excited electron states (1000 levels per eV in Au\n24+) and a strong configuration mixing. This complexity enables one to use\nstatistical methods to analyze the system. The orbital occupation numbers obey\nthe Fermi-Dirac distribution, and temperature can be introduced. We show that\nradiative capture of electrons through the multielectron resonant states is\nstrongly enhanced compared to the direct radiative recombination.",
