Observation of Trielectronic Recombination in Be-like Cl Ions
Recombination involving the core excitation of two electrons, which may be termed trielectronic recombination, has been experimentally identified for the first time. Using [Formula presented] ions circulating in the TSR heavy-ion storage ring, we have observed surprisingly strong low-energy trielect...
