摘　　要：研究了高电荷态离子129Xe28+轰击金属Au和Mo表面产生的特征X射线谱。实验结果表明,在入射离子的电荷态和能量相同的条件下,对于核电荷数较小、原子质量较轻的靶原子,只有其内壳层的电子才能被激发而产生X射线,而核电荷数较大、原子质量较重的靶原子只有其较外壳层的电子能被激发而产生X射线。特征X射线的产额随入射离子动能的增加而增加。It was studied that the characteristic X ray spectra produced by the interaction of highly charged ions of 129Xe28＋ with metallic surface of Au and Mo.The experimental result shows that the target atom with less core charged amounts and less atom mass can stimulate inner layer electron to produce X ray when the incident ion has the same charge and the same energy.On the other hand the target atom with more core charge amounts and atom mass can only stimulate outer layer electron to produce X ray.The yield of the characteristic X ray increases with the increase of the iron＇s kinetic energy.
