TLDR
The fourth international LTE opacity workshop and code comparison study, WorkOp-IV, was held in Madrid in 1997 as mentioned in this paper, with a focus on iron opacities, and the astrophysically important photon absorption region between 50 and 80 eV was emphasized for a sequence of iron plasmas at densities and temperatures that produce nearly the same average ionization stage (Z ∗ ∼8.6).
Abstract
The fourth international LTE opacity workshop and code comparison study, WorkOp-IV, was held in Madrid in 1997. Results of this workshop are summarized with a focus on iron opacities. In particular, the astrophysically important photon absorption region between 50 and 80 eV is emphasized for a sequence of iron plasmas at densities and temperatures that produce nearly the same average ionization stage (Z ∗ ∼8.6) . Experimental data that addressed this spectral region is also reviewed.

Statistical line-by-line model for atomic spectra in intermediate coupling

TL;DR: In this paper, a statistical method to simulate detailed line accounting (DLA) calculations of complex spectra is proposed, which is based on the recently developed partially resolved transition array model.

Extreme ultraviolet probing of laser ablation

Lauren Hobbs
TL;DR: In this article, the use of extreme ultraviolet (EUV) sources in probing laser ablation and material opacity is described, where both broad and narrowband EUV wavelength probes for benchmarking theoretical models of opacity are presented.

Improvements in the phase-amplitude method for calculating free–free gaunt factors and spherical bessel functions of high angular momentum

TL;DR: In this article, a non-recursive method for calculating spherical Bessel functions of large order is presented and contrasted to earlier schemes, where the amplitude and phase of the Bessel function is modelled in terms of a wave function.

A quantitative study of some sources of uncertainty in opacity measurements

TL;DR: In this article, the authors discuss some sources of uncertainty in absorption-spectroscopy experiments, concerning areal mass, background emission, intensity of the backlighter and self-emission of the plasma.

Analysis of the influence of the plasma thermodynamic regime in the spectrally resolved and mean radiative opacity calculations of carbon plasmas in a wide range of density and temperature

TL;DR: In this article, the spectrally resolved, multigroup and mean radiative opacities of carbon plasmas are calculated for a wide range of plasma conditions which cover situations where corona, local thermodynamic and non-local thermodynamic equilibrium regimes are found.
