Formation of Carbonic Cluster Ions at the Ionization of Fullerenes and Multiatomic Molecules of Hydrocarbons

Abstract

Formation probability of carbonic ionized clusters arising from the collisions between multiply charged ions and fullerene – C60, toluene – C7H8, benzene – C6H6 and butane – C4H10 molecules has been measured. He2+ and Ar6+ projectile ions have been used for the ionization and following fragmentation of polyatomic molecules. The charge state analysis of projectile ions after collisions made it possible to control the minimal number of electrons removed from the target molecule and, as a result, the qualitative control of its excitation energy. The recoil fragment ions formed at target molecule dissociation have been analyzed on mass and charge by time of flight system (TOF).
