The highly charged ions129Xe27+ impacting on Ni surface are neutralized by resonant capturing of electrons of metallic conduction band and release of potential energies. The multiply excited Xe atoms are formed and the outer-shell electrons are de-excited by emitting infrared photons. In the process, within femtoseconds, the projectile total energies are deposited on the target surface (on the nanometers scale), which excites and ionizes the target atoms. The characteristic transitions between complex configurations of atoms and ions occur, especially the characteristic forbidden transition (M1 and E2) of NiⅠand NiⅡ, and the X-ray emission. The increasing of X-ray yield per ion with kinetic energies of projectile was found.
