TL;DR: In this paper, the relative intensity of the resonance and intercombination line in neon-like Fe XVII, located at 15.01 and 15.26 A, respectively, has been measured at the Lawrence Livermore National Laboratory electron beam ion trap EBIT-II as a function of the relative abundance of Fe XVI.

TL;DR: The measurements provide benchmarks for the development of theoretical approaches, such as relativistic many-body perturbation theory and large-scale configuration-interaction calculations, that attempt to account for electron correlations in very highly charged ions.

TL;DR: In this paper, the polarization of the 2p{sub 3/2}{yields}1s{sub 1/2} Lyman-{alpha}{sub 1} x-ray line of hydrogen-like Ar{sup 17+} and Fe{sup 25+} at electron-impact energies ranging from 7 to 25 threshold units was measured.

TL;DR: In this paper, the uncertainties in the measurements are less than 8% for the helium-like Fe transitions and between 11% and 15% for lithium-like F transitions together with a 3% systematic uncertainty from the normalization to theoretical radiative recombination cross sections.

TL;DR: In this article, the authors measured relative cross sections for Fe XXIV line emission at electron energies between 0.7 and 3.0 keV using the Electron Beam Ion Trap facility at Lawrence Livermore National Laboratory.
