The characteristic X-ray spectra produced by the impact of Xe-129(26+) with kinetic energies from 350 to 600 keV and from 1.8 to 3.9 MeV on Au surface are measured. It is found that Xe-129(26+) with kinetic energies from 350 to 600 keV can excite only the characteristic X-ray spectra of M alpha of Au, but Xe-129(26+) with kinetic energies from 1.8 to 3.9 MeV can excite the characteristic X-ray spectra of M zeta, M alpha, M gamma and M delta. The relation between the characteristic X-ray intensity, the ratio of X-ray yield and the ion kinetic energy is analyzed. The kinetic energy threshold of L-X-ray of Xe emitted by Xe26+ is estimated.
