利用低速(V ≈0.01VBohr)高电荷态Krq+(q=8,10,13,15,17)离子轰击金属Al表面,获得了碰撞过程产生的300—600 nm的光谱.实验结果表明:低能大流强(μA/cm2量级)离子束入射金属表面,可产生溅射原子、离子和入射离子中性化后发射的可见光.随着入射离子势能(电荷态)增加,碰撞过程中发射谱线的强度增强.与激发态3d能级相比,较高的势能可以有效地激发Al原子的电子到较高4s能级.

The spectrum range from 300 to 600 nm is measured with low energy (V ≈0.01 VBohr) highly charged Krq+ions (q=8, 10, 13, 15, 17) impacted on Al surface. The results show that the spectral lines are induced by the impact of low-energy ions on Al surface, and that these lines belong to the sputtered atoms, ions, and the incident ions which are neutralized. The intensity of emission line increases with the projectile potential. The electron of Al can be efficiently excited to the 4s state by the higher potential energy compared with the excited state of 3d.
