Ed. Emmons et al., Multiple-electron capture processes in 70-keV N-15(7+)+Ar collisions: A triple-coincidence study, PHYS REV A, 60(6), 1999, pp. 4616-4626
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].
