Ion-Solid and Ion-Molecule Collisions
Part of the Lecture Notes in Physics book series (LNP, volume 294)


Time-of-flight (TOF) spectroscopy has been applied to the identification and study of ionic species produced in fast ion-molecule collisions. By optimizing the resolution of the TOF spectrometer employed, kinetic energies have been determined for the dissociation products of simple diatomic molecules ranging in charge from 1+ to 5+. Various spectral features are compared for monatomic and diatomic targets, and the characteristics of the fragmentation patterns for the complex molecule SF6 produced in He+ and Ar13+ collisions are examined.
