The cluster-ion-beam apparatus with a discharge-flow ion source was developed and ion-molecule reactions of ArN_2^+ with simple aliphatic hydrocarbons, Kr, and CO_2 were studied. A characteristic reactivity of cluster ions, which is different from that of free ions, was found. This apparatus was succussfully applied to the study of ion-molecule reactions of CO_2^+ and CF_3^+ with simple aliphatic hydrocarbons and such aromatic compounds as benzene derivatives, and the formation processes of cluster ions were examined. For example, we found that cluster ions were produced in the CO_2^+/CH_4, CF_3^+/C_2H_2, CF_3^+/PhX(X=C_2H,CN,OCH_3, COH,COCH_3, COOCH_3)reactions : e.g.,CF_3^++C_2H_2*CF_3C_2H_2^+ (1)A systematic optical study on rare gas heterocluster ions was also performed using a highpressure discharge-flow apparatus. New ArKr^+ and KrXe^+ emissions were observed from the Ar afterglow reaction of Kr and Kr afterglow reaction of Xe, and their electronic structures wered etermined. At higher rare gas stagnation pressures, new bound-free transitions of rare gas heterotrimer ions such as HeAr_2^+ were found. These emissions are expected to be useful as new excimer lasers in the vacuum ultraviolet region.

研制了放电流离子源团簇离子束装置，研究了ArN_2^+与简单脂肪烃、Kr和CO_2的离子-分子反应。发现团簇离子具有不同于自由离子的特征反应性，并成功地应用于CO_2^+和CF_3^+与简单脂肪烃及苯衍生物等芳香族化合物的离子-分子反应研究，考察了团簇离子的形成过程。例如，我们发现在CO_2^+/CH_4，CF_3^+/C_2H_2，CF_3 ^+/PhX（X= C_2H，CN，OCH_3，COH，COCH_3，COOCH_3）反应中产生了团簇离子：例如，CF_3^++C_2H_2*CF_3C_2H_2^+（1）用高压放电流动装置对稀有气体异质团簇离子进行了系统的光学研究。从Ar与Kr的余辉反应和Kr与Kr的余辉反应中观察到了新的ArKr^+和KrO 2 ^+发射，并测定了它们的电子结构。在较高的惰性气体滞止压力下，发现了HeAr_2^+等稀有气体异三聚体离子的束缚-自由跃迁，这些跃迁有望成为真空紫外区的新型准分子激光器。
