Research Abstract

We have developed the ion beam scattering apparatus in which both the internal state and translational energy of the molecular ions can be controlled. The methyl radical cations and ally radical cations in specific rovibrational states were generated by the ion source, and they were efficiently transferred into the reaction cell through the RF octapole ion guide. The resolution of the collision energy was fairly good even in the low collision energy region down to 1 eV. The energy width was narrow enough to enable us to elucidate the organic ion-molecular reaction systems from the view point of the gas-phase reaction dynamics by applying the apparatus.
