高电荷态离子Ar17+与Mo表面作用过程中的X射线发射
X-Ray in Highly Charged Ar17+Ion Interacting with Mo Surface
【摘要】 观测了低速 (小于Bohr速度 )高电荷Ar17+离子与金属Mo表面相互作用的X射线发射 ,以及ArKα ,KβX射线强度随入射离子动能的变化 .
【Abstract】 The X-ray emission from the highly charged Ar 17+ ion interacting with Mo surface are measured on the 14.5GHz Electron Cyclotron Resonance ion source facility at Institute of Modern, the Chinese Academy of Sciences in Lanzhou. Ar 17+ ions came from Electron Cyclotron Resonance ion source and impacted on Mo surface.The incident ion with vacancy of inner shell captures electrons emitted from surface into highly excited Rydberg states, outer shell electron cascades into K vacancy giving rise to Kα X-ray emission of the incidentionsions.
