Abstract:Using flat-field grating Spectrometer, the ions lines with wavelength between 5 and 60 nm were measured, which were produced by the interaction of circularly polarized 35 femtosecond ultraintense and ultrashort laser-pulse with 5 mm length xenon at the pressure 2 and 3 kPa respectively. The highest transition is the XeⅧ:4d105s(2S1/2)—4d95s5p(2P3/2) line at wavelength 17.085 6 nm at 2 kPa and 3 kPa, the highest transition is 11.343 nm line of XeⅦ 4d105s2(1S0)—4d95s25f(3P1) transition. The xenon is ionized to XeⅦ,XeⅧ and XeⅨ at both pressure.
