【摘要】 对Ar²⁺与Li,Na碰撞过程中由于单电子俘获而产生的Arll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。更多还原

【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 AE 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.更多还原
