Assistance of core-ion dissociation by energy transmission from solvent molecules in N3O3-(NO)(n) (n=0-38) impact onto silicon surface
A size-selected cluster anion, N3O3-(NO)(n) (n = 0-38), was allowed to collide onto a silicon surface, and the product anions, NO2-, N2O2- and N3O3-(NO)(m) (m = 0-2), from the surface were observed mass-spectroscopically. The branching fractions of the product anions were measured as functions of the energy of the incoming parent cluster anion and the size, n. It was found that NO molecules located in the vicinity of the core ion, N3O3-, transmit their kinetic energy to N3O3 most efficiently.
