چکیده انگلیسی
At the Berlin Electron Beam Ion Trap facility we investigated the radiation of highly charged xenon ions in the extreme ultraviolet wavelength range using a 2Â m grazing incidence spectrometer. For Rb-like Xe17+ to Cu-like Xe25+ ions 37 individual lines have been registered in the range between 90 and 240Â Ã
and identified by performing atomic structure calculations with the HULLAC code. The 4s-4p resonance lines of Cu-like and Zn-like Xe ions are found to be in good agreement with measurements at tokamaks and MCDF calculations. The experimental wavelengths for ions involving a larger number of electrons in the n = 4 shell deviate slightly from the predicted values. Several lines observed with the BerlinEBIT had been previously seen but not identified at the tokamak and can now be classified.
