高电荷态离子N⁶⁺、O⁵⁺、Ne⁴⁺与He原子碰撞激发过程的实验研究

摘要: 利用电子迥旋共振(ECR)多电荷离子源产生的高电荷态离子束和LHT—30VUV真空紫外单色仪,研究了N~6+、O~5+、Ne~4+与He碰撞激发过程,观察到单电子俘获、双电子俘获和入射离子直接激发三种激发过程。 We have investigated the excitation processes in collisions between N~(6+), O~(5+), Ne~(4+) andHe by using the ECR ionic source and the LHT-30 VUV Monochromator. The emission spectra showthat there are three channels of excitation in the N~(6+)+He collision system: (1) Single electroncapture into excited states; (2) Double electron capture into excited states; (3) Direct excitation ofincident ions.
