摘要: 对Ar2+与Li,Na碰撞过程中由于单电子俘获而产生的ArII谱线进行了绝对测量,给出各谱线的发射截面数据。入射离子能量为40—300keV。从发射截面对势能亏损的依赖关系,发现对应中等△E(>0)值的过程具有较大的截面。并且还发现与观察到的光谱线相应的激发态属于一个电子组态中高J量子数的态。
Abstract: Absolute measurements of emission cross sections have been performed for the lines from Arll excited states in Ar2++Li and Ar2++Na collision. The energy of incedent ions ranged from 40 keV to 300 keV. The dependence of the emission cross sections on the energy defect △E is discussed. We find that the processes with intermediate △E(>0) have larger cross sections. We also find that the excited states correlated to the observed lines belong to the high J quantum numbers in an electron configuration.
