Abstract

The gas-phase reaction of translationally cold Ar²⁺ ( ¹S₀) ions with C₆₀ has been studied using a selected-ion flow tube (SIFT) apparatus. Amongst several product channels detected, which arose from competing reactions of contaminants (N₂, O₂, H₂O) and from the He buffer gas itself as well as from the target process Ar²⁺+C₆₀, we observed an apparently minor but unambiguous signal due to a C₆₀³⁺ product ion. We surmise that this product channel arises from Ar²⁺ ( ¹S₀)+C₆₀ in a bimolecular fashion, most probably by an initial (and highly exothermic) direct double electron transfer leading to the generation of either highly excited (C₆₀ ²⁺)^* or of electronically excited (Ar) ^*. Trication formation from either of these possible high-energy intermediates would then follow according to either an autoionization or a Penning ionization mechanism.
