Resumen:
Recombination involving the core excitation of two electrons, which may
be termed trielectronic recombination, has been experimentally
identified for the first time. Using Cl13+ ions circulating
in the TSR heavy-ion storage ring, we have observed surprisingly strong
low-energy trielectronic recombination resonances, comparable to the
dielectronic process. At higher electron-ion collision energies,
trielectronic recombination is suppressed due to the autoionization of
the triply excited intermediate state into excited final states. The
formation of the intermediate state depends sensitively on configuration
mixing, making trielectronic recombination a challenge to
atomic-structure calculations.
