摘      要：The X-rays with energy from 1 keV to 60 keV in the interaction of highly charged ions (HCI) with a variety of solid surfaces were investigated at the research platform for atomic physics with the electron cyclone resonance (ECR) ion resource at IMP. We altered the projectile kinetic energy from 150 keV to about 400 keV. The X-ray excited by the projectile with the surface is shown in Fig.1, and a threshold of the projectile kinetic energy for this excitation is observed. Combining the colliding theory of classic electrodynamics with the concept of quantized orbits, we crudely give this threshold energy Tm as follows,
