Absolute cross sections for multielectron processes in low-energy Arq+-Ar collisions as measured with a new technique

Using low-energy recoil ions produced by 110 MeV C 4+ projectiles the authors have applied time-of-flight techniques to identify simultaneously q, r and s, measuring cross sections for the Ar q+ +Ar to Ar r+ +Ar s+ +(r+s-q)e - reactions at 1.8 q keV. Cases with up to five electrons transferred were observed.
