- W3025851892 abstract "用速度不同的（动能EK= 272和357 keV, 速度v=1.14×106和1.72×106 m/s）的高电荷态离子40Ar17+分别入射金属Be表面， 同时测量这种相互作用过程中产生的近红外光谱线和X射线谱。实验结果表明, 在低速范围内（速度小于玻尔速度vBohr=2.19×106 m/s）， 速度较小的40Ar17+离子在到达金属的表面临界距离Rc到进入表面（2—3原子层）的进程中， 形成了较多的高激发态Ar原子， 其退激辐射较强的光谱线， 进而验证了经典过垒模型。 The highly charged ion 40Ar17+ (kinetic energy EK=272 keV, velocity v=1.14×106 m/s and EK=357 keV, v=1.72×106 m/s) impacts on the surface of metal Be, and the atomic infrared light line and Xray spectrum are simultaneously measured. The experimental results show that in the low velocity region (less than vBohr), the highly charged ion with smaller velocity from a critical distance Rc to penetrate into the bulk formed more multipleexcited Ar atoms and the spectrum intensities of decay radiation are greater, which verifies the classical over the barrier model." @default.
