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.

我们研制了分子离子内部状态和平移能量均可控制的离子束散射装置。该离子源产生特定振转态的甲基自由基阳离子和烯丙基自由基阳离子，并通过射频八极离子导向器将其有效地转移到反应池中。的碰撞能量的分辨率是相当不错的，即使在低碰撞能量区域下降到1 eV。能量宽度足够窄，使我们能够阐明有机离子-分子反应系统的气相反应动力学的观点，通过应用该装置。
