LABORATORY MEASUREMENTS OF Fe XXIV L-SHELL LINE EMISSION
نویسندگان
چکیده
Recent ASCA spectra exhibit discrepancies with the relative line intensities of various Fe XXIII and XXIV L-shell emission lines predicted by standard plasma emission codes. To address this issue, we have carried out a series of high-resolution, broadband measurements of Fe XXIV line emission using an electron beam ion trap facility. X-ray lines produced in the trap are detected and resolved using Bragg crystal spectrometers. We report measurements of 33 2 and 43 2 transitions, which result primarily from electron impact excitation. Overall, good agreement is found with distorted wave calculations. Subject headings: atomic data— atomic processes—methods: laboratory—X-rays: general

MEASUREMENTS OF Fe XXIV LINE EMISSION : 3 ] 2 TRANSITIONS NEAR EXCITATION THRESHOLD
Using the Electron Beam Ion Trap facility at Lawrence Livermore National Laboratory, we have measured relative cross sections for Fe XXIV line emission at electron energies between 0.7 and 3.0 keV. The measurements include line formation by direct electron impact excitation (DE), radiative cascades, resonant excitation (RE), and dielectronic recombination (DR) satellites with captured electrons...
متن کاملFe L-Shell Density Diagnostics in Theory and Practice
We provide a discussion of the density and photoexcitation sensitivity of the X-ray spectra of Fe L-shell ions (Fe XVII–Fe XXIV) calculated with the Livermore X-ray Spectral Synthesizer, a suite of IDL codes that calculates spectral models of highly charged ions based primarily on HULLAC atomic data. These models are applicable to collisionally ionized laboratory or cosmic plasmas with electron...
متن کاملTesting the Seyfert unification theory : Chandra HETGS observations of NGC 1068
We present spatially resolved Chandra HETGS observations of the Seyfert 2 galaxy NGC 1068. Xray imaging and high resolution spectroscopy are used to test the Seyfert unification theory. Fe Kα emission is concentrated in the nuclear region, as are neutral and ionized continuum reflection. This is consistent with reprocessing of emission from a luminous, hidden X-ray source by the obscuring molec...
متن کاملLaboratory measurements of the x-ray line emission from neon-like Fe XVII
We have conducted a systematic study of the dominant x-ray line emission from Fe XVII. These studies include relative line intensities in the optically thin limit, intensities in the presence of radiation from satellite lines from lower charge states of iron, and the absolute excitation cross sections of some of the strongest lines. These measurements were conducted at the Lawrence Livermore Na...
متن کاملAtomic data for the K - vacancy states of Fe xxiv
As part of a project to compute improved atomic data for the spectral modeling of iron K lines, we report extensive calculations and comparisons of atomic data for K-vacancy states in Fe xxiv. The data sets include: (i) energy levels, line wavelengths, radiative and Auger rates; (ii) inner-shell electron impact excitation rates and (iii) fine structure inner-shell photoionization cross sections...
