测量了动能为2.0 MeV的高电荷态离子152Eu20+入射Au表面产生的Au的Mζ,Mα和Mδ特征X射线和Eu的Mα-X射线.对X射线产生的微观机制进行了初步分析,并通过半经典两体碰撞近似,估算了Eu20+与Au作用产生的Au的M-X射线和Eu的M-X射线的动能阈值.此结果对高电荷态离子与固体表面相互作用的动力学过程的研究以及在辐射能量转换效率研究中如何选取合适的弹靶组合具有重要的参考价值.

It is measured that the characteristic X-ray spectra of Mζ, Mαand Mδof Au and the characteristic X-ray spectra of Mαof Eu produced by the interaction of highly charged ions of 152Eu20+with kinetic energy 2.0 MeV on Au surface. The micro-mechanism of X-ray excitation is preliminary analyzed. The kinetic energy threshold of M-X ray of Au and M-X ray of Eu emitted by Eu20+with Au is estimated by semiclassical approximation theory of binary collision. The threshold has important referenced value in the study on dynamics of the interaction of highly charged ions with solid surface and on how to choose better target and projectile combination in the conversion e?ciency of radiation energy.
