摘要

X-ray spectra of highly-ionized xenon and krypton measured in a laser-irradiated gas jet are presented with a main purpose of line identification. The spectral range of 0.5 to 1 nm was covered using two flat Brag, crystal spectrographs. The very rich spectra of xenon cover the transitions 3p-nd and 3d-nf. with n = 5 to 10, of Xe26+ to Xe30+ (Ni-like to Cr-like). Transitions 2p-nd and 2s-np with n = 3, 4 of Kr24+ to Kr28+ (Mg-like to O-like) have also been recorded, in a range covering some unidentified lines. Ab initio detailed calculations performed with the RELAC code have permitted to identify lines of Xe and Kr, including transitions which were measured but not identified until now. Ionic fractions were deduced by adjusting the experimental spectra with a least-squares fit based on the RELAC data. [References: 34]
