SynopsisWe have studied multiple ionization and multifragmentation of a chlorofluorocarbon molecule, CH 2 FCF 3 , induced by collisions of 580-keV C + ions. Coincidence measurements of product ions and the number of emitted electrons from CH 2 FCF 3 were performed under charge-changing conditions of C + → C q+ (q = 0, 2, 3). A fully inclusive measurement regardless of outgoing projectile charge state was also performed by making coincidence with a pulsed ion beam. Mass distributions of fragment ions and number distributions of emitted electrons were both found to change greatly according to charge-changing conditions. Highly multiple ionization emitting up to about 10 electrons was observed in electron loss collisions.
