Abstract: Collisional processes of${\rm{I}}_2^- ({\rm{CO}}_2)_n$with a silicon surface were investigated. Size-selected${\rm{I}}_2^- ({\rm{CO}}_2)_n$(n=0–30)were allowed to collide with a silicon surface at collision energies per${\rm{I}}_2^-$of 1–150 eV at almost normal incidence angles. All the anions scattered from the surface wereI−,I−(CO2),I−(CO2)2,${\rm{I}}_2^-$,${\rm{I}}_2^- ({\rm{CO}}_2)$, and${\rm{I}}_0^- ({\rm{CO}}_2)_2$. The molecular dynamics simulation revealed that the dissociation of${\rm{I}}_2^-$occurs through vibrational and rotational excitation. The${\rm{I}}_2^-$dissociation was found to be either retarded or accelerated by the presence of the solventCO2molecules. The solvation effects on the dissociation of${\rm{I}}_2^-$were explained in terms of energy transfer between${\rm{I}}_2^-$andCO2solvent molecules and a complex formed on the surface at the moment of the collision.
