Fragmentation patterns of ionized C5Q+clusters (Q= 1 → 4)

This is the authors' abstract. We don't add key points for this paper.

A new experimental set-up has been built allowing, for the first time, the complete collection, event by event, of all fragments resulting from the dissociation of C 5 Q + clusters ( Q = 1 → 4). These ionized species were created either by dissociative excitation ( Q = 1) or ionization ( Q = 2, 3, 4 for single, double and triple ionization respectively) of incident 10 MeV C 5 + ions colliding with an He target. The fragmentation pattern of C 5 + is found to be radically different from the one observed in photoexcitation or in low velocity collisions. Results concerning the fragmentation of C 5 Q + clusters with Q ⩾ 2, for which no data existed up to now, exhibit a large variety in the possible fragmentation channels.
