中文摘要：
研究了高电荷态离子129Xeq＋（q=25,26,27）入射金属Mo表面产生的特征X射线谱.实验结果表明,在束流强度小于120nA条件下,高电荷态离子129Xeq＋可以激发Mo的L壳层特征X射线谱.单离子X射线相对产额可达10-8量级,特征X射线的相对产额随入射离子的动能和电荷态（势能）的增加而增加.通过Mo原子的Lα1特征X射线谱,利用Heisenberg不确定关系对Mo原子的第M能级寿命进行了估算.
英文摘要：
We studied the characteristic X-ray spectra produced by the interaction of highly charged ions of 129 Xeq ＋ （q = 25,26, 27）with surface of metallic Mo. The experimental result shows that highly charged ions can excite the characteristic X-ray spectra of L-shell of Mo when the beam’s intensity is not more than 120 nA. The X-ray yield of single ion reaches a quantitative level of 10 -8 and increases with the increment of the ion’s kinetic energy and ionic charge （potential energy）. By measuring the X-ray spectra of Mo-Lα1 ,the M-level lifetime of Mo atom is estimated by using Heisenberg uncertainty relation.
