Three-body fragmentation dynamics of CH2CCH2 3+ investigated by Ne8+ impact

The three-body fragmentation dynamics of triply charged allene (CH2CCH23+) induced by 50-keV/u Ne8+ ion impact is studied by measuring the charged fragments in triple coincidence using reaction microscope. We focus on the fragmentation dynamics of two completely measured fragmentation channels, H++CH++C2H2+ and H++CH2++C2H+. Both concerted and sequential dissociation mechanisms are observed for these two channels. The estimation of relative contributions of different fragmentation pathways is presented.
