摘要

Multielectron coincidence data for triple ionization of krypton have been recorded above the 3d ionization threshold at two photon energies (140 and 150 eV). Three principal transition pathways have been observed, two involving double Auger transitions from Kr(+), and one involving single Auger transitions from Kr(2+) created by direct single-photon double ionization. The decay of the 3d(9) (2)D(5/2,3/2) states in Kr(+) has been analyzed in some detail and is found to be strongly dominated by cascade processes where two electrons with well-defined energies are emitted. The decay paths leading to the 4s(2)4p(3) (4)S, (2)D, and (2)P states of Kr(3+) are analyzed and energies of seven intermediate states in Kr(2+) are given. A preliminary investigation of the decay paths from Kr(+) 3d (9)4p(5)nl shake-up states has also been carried out.
