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.

开发了带有排放流离子源的簇 - 离子束设备，并研究了ARN_2^+的离子 - 分子反应与简单的脂肪族烃，KR和CO_2。簇离子的特征反应性与自由离子的反应性不同。该设备可成功地用于研究CO_2^+和CF_3^+与简单脂肪族烃的离子 - 分子反应，以及苯衍生物等芳香族化合物，并检查了群体离子的形成过程。 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还使用高压排放流动器进行了稀有气体杂簇离子的研究。从Xe的Kr和Kr余辉反应的Ar余辉反应中观察到了新的Arkr^+和Krxe^+排放，其电子结构却被忽略了。在较高的稀有气体停滞压力下，发现了稀有气体异构体离子（例如HEAR_2^+）的新无界过渡。这些排放量预计将作为真空紫外线区域的新准分子激光器有用。
