X-Ray Spectra of Hydrogen-Like and Helium-Like Argon Ions on Solid Surfaces

14-GHz electron cyclotron resonance ion source at the Heavy Ion Research Facility National Laboratory in Lanzhou has been used to investigate x-rays from the interaction of slow highly charged Ar17+and Ar16+ions for different energies with Be, Al, Ni, Mo and Au surfaces. Interaction of Ar17+ and Ar16+ ions with Metallic Surfaces for a wide range of energies has been studied by measuring the resulting x-ray emission. The characteristic features of the x-ray spectra have been explained.
