摘　　要：利用德国波恩2.3GeV同步辐射加速器作为辐射源,采用飞行时间法测得软X射线引起氲原子内壳电离后,电离产物的飞行时间谱。由此获得原子电离后的平衡电荷态分布。Monochromatic x-rays from the Bonn 2.3GeV-Synchrotron were employed for inner shell excitation of argon. The vacancies are filled via a branching cascade which leads to the emission of a number of electrons. In order to study the equilibrium charge distribution of ionic argon, a time of flight mass spectrometer was set up and used to measure the resulting ionic charge spectra with photoenergies near to the k-absorption edge of argon. The energy dependence of relative charge probabilities is presented
