【 摘 要 】

Synopsis Series of inner-shell dielectronic resonances were measured in the 7-20-keV x-ray spectra of highly charged tungsten and iridium ions produced in ion traps by highly dense electron beams. A detailed analysis of the spectra with a non-Maxwellian collisional-radiative model allowed us to reliably assign the experimentally observed features.
