Ar^(16＋)与Zr作用产生的X射线谱

X-ray Spectrum Produced by Interaction of Ar^(16+) With Zr

本工作对超导离子源(SECRAL)上的10~20 kV/q Ar16+和Ar17+入射到金属Zr表面进行实验研究。实验结果表明,高电荷态Ar16+在金属表面存在着多电子激发过程。Ar空心原子的K层发射X射线强度随入射离子的动能减少,靶原子Zr的L壳层发射X射线强度随入射离子动能的增加而增强。Ar17+单离子的K-αX射线产额比Ar16+单离子的K-αX射线产额大5个数量级。

The 10-20 kV/q Ar^16＋ and Ar^17＋ ions were produced by SECRAL incidence onto metallic surface of Zr. The multi-electron excitation occurred in the process neutralization of the highly charged Ar^16＋ ions in metallic surface, which possibly produced vacancy in the K shell. Kα-X-ray yield per ion for Ar^17＋ has five orders of magnitude greater than that for Ar^16＋. The intensity of X-ray of the Ar hollow atom decreases with kinetic energy increase, and the intensity of X-ray from L shell of the target atom Zr increases with kinetic energy increase.
