【摘要】将超导离子源提供的10—20keV/qAr16+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-X射线产额比Ar16+单离子的Kα-X射线产额大5个数量级.更多还原

【Abstract】 The 10—20?qkeV 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+.更多还原
