单色光激发的轻元素X射线分析

Enhanced-Hydrogenation of Bombarded Surface of Mg-NiEutectic Alloy

利用同步辐射单色光和质子激发的Ｘ射线作为可选择能量的单色光源，对Ｋ、Ｃａ．Ｔｉ轻元素进行Ｘ荧光分析．实验结果表明，它不仅可以降低轫致辐射本底，还可用通过选择合适的激发能量排除某些元素的干扰，从而使Ｋ、Ｃａ、Ｄｉ元素分析灵敏度得到明显的提高．

Hydrogenated effect of the Mg-Ni alloy surface caused by 27keV Ar+ ions bombardment has been studied. The enhancement of hydrogenated effect depends on fluence, A model of change-surface of catalyzed-phase due to ion bombardment is proposed to describe this phenomenon of hydrogenated enhancement in the present Work.
