Multiple-electron capture processes in 70-keV N-15(7+)+Ar collisions: A triple-coincidence study

Double- through quintuple-electron capture processes in the 70-keV N-15(7+) + Ar collision system have been investigated by means of time-of-flight tr iple-coincidence measurements of Anger electrons, scattered projectile, and target recoil ions. Subpartial Auger-electron spectra corresponding to spe cific pairs of final projectile and recoil-ion charge states have been obta ined and discussed within the framework of the extended classical overbarri er model [A. Niehaus, J. Phys. B 19, 2925 (1986)]. By allowing for target e xcitation the model accounts reasonably well for the observed initial popul ations. Possible relaxation pathways of the populated multiply excited conf igurations have been identified. Measurements of this type allow a deeper u nderstanding of the production and relaxation pathways of these configurati ons. [S1050-2947(99)06112-0].
