Abstract

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 Xray 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 multipleexcited Ar atoms and the spectrum intensities of decay radiation are greater, which verifies the classical over the barrier model.
