By use of optical spectrum technology, the spectra of X-ray induced by highly charged 40Arq+ ions interacting with Au surface have been studied. The results show that the argon Kα X-ray were emitted from the hollow atoms formed below the surface. There is a process of multi-electron exciting in neutralization of the Ar16+ion, with electronic con-figuration 1s2 in its ground state below the solid surface. The yield of the projectile Kα X-ray is related to its initial electronic configuration, and the yield of the target X-ray is related to the projectile kinetic energy.

The highly charged ion 40Ar16+ with the velocity (kinetic energy EK=150 keV, velocity V=8.5×105 m/s) smaller than Bohr velocity (VBohr=2.9×106 m/s) was found to hove impacts on the surfaces of metals Ni, Mo, Au and Al, and the Ar atomic infrared light lines and X-rays spectra were simultaneously measured. The experimental results show that the highly charged ion that captures electrons is neutralized, and the multiply-excited hollow atom forms. The hollow atom cascade decay radiates lights from infrared to X-ray spectrum. The intensity of infrared lights shows that the metallic work functions play an important role in the neutralization process of highly charged ions during their interaction with metallic surfaces, which verifies the classical over-the-barrier model.

The total reaction cross section (1724±93 mb) of 17B at the energy of 43.7 A MeV on C target has been measured by using the transmission method at the Radioactive Ion Beam line in Lanzhou (RIBLL). Assuming 17B consists of a core 15B plus two halo neutrons,the total cross section of 17B on C target was calculated with the zero-range Glauber model,where double Gaussian density distributions and Gaussian plus HO density distributions were used. It can fit the experimental data very well. The characteristic of halo structure for 17B was found with a large diffusion of the neutrons density distribution.

The X-ray spectra induced by the highly charged xenon and argon ions impinging on a tantalum surface are reported. The experiment was done at the ECR ion source of H1RFL. It is found that the yield of the tantalum M-X rays increases intensively as the projectile kinetic energy increasing. Moreover, the tantalum M-X ray induced by the xenon ions is higher in energy and broader in width than that induced by the argon ions (as shown in Figs. 1 and 2).

The light spectrum of a wavelength from 200 to 1 000 nm emitted from Ti-atoms sputtered from the solid surface of Ti-target by slow highly charged ions (SHCI) has been done on the atomic physics experimental setup at the lab of ECRIS (14.5 GHz) in IMP (shown in Fig.1). The result shows that the atoms of the solid material can be strongly excited by the SHCIs even though the intensity of the incident ions is lower as about
