Ar16+和Ar17+离子与Zr作用产生的X射线谱

将超导离子源提供的10—20keV/q Ar¹⁶⁺和Ar¹⁷⁺离子入射到Zr金属表面，在相互作用中产生的X射线谱表明，高电荷态Ar¹⁶⁺离子在金属表面中性化过程中有可能存在多电子激发，使Ar¹⁶⁺的K壳层电子被激发形成空穴，在退激过程中发射特征Kα-X射线.空心原子Ar的K层发射X射线强度随入射离子的动能而减弱，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⁺的单离子的Kα-关键词：高电荷态离子空心原子X射线

X-ray spectra produced by interaction of Ar16+ and Ar17+ with Zr

The 10—20qkeV Ar¹⁶⁺ and Ar¹⁷⁺ ions produced by SECRAL enter on metallic surface of Zr. In this interaction，the multi-electron excitation possibly occurred in the neutralization of the highly charged Ar¹⁶⁺ ions，which produced vacancy in the K shell. Electron of the high n state de-excited to K vacancy gives off X-ray. The experimental results show that X-ray intensities for the Ar hollow atom decrease with increase of incidence energy，and Lβ X-ray intensities of target atom Zr increase with increasing incidence energy. Kα X-ray yield per ion for Ar¹⁷⁺ was five orders of magnitude greater than that for Ar¹⁶⁺.
