高电荷态离子N^(6+)、O^(5+)、Ne^(4+)与He原子碰撞激发过程的实验研究

Highly Charged Ions N^(6+),O^(5+), Ne^(4+) Collision with Atom He into Excited States

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.
