We show that a dense spectrum of chaotic multiply-excited eigenstates canplay a major role in collision processes involving many-electron multichargedions. A statistical theory based on chaotic properties of the eigenstatesenables one to obtain relevant energy-averaged cross sections in terms of sumsover single-electron orbitals. Our calculation of the low-energy electronrecombination of Au$^{25+}$ shows that the resonant process is 200 times moreintense than direct radiative recombination, which explains the recentexperimental results of Hoffknecht {\em et al.} [J. Phys. B {\bf 31}, 2415(1998)].Comment: 9 pages, including 1 figure, REVTe
