title: Dirac–Fock and Δ<em>E</em><sub>SCF</sub> thresholds in eV used compared with available experiment

description: <b>Table 1.</b> Dirac–Fock and Δ<em>E</em><sub>SCF</sub> thresholds in eV used compared with available experiment. <strong>Abstract</strong> The photoionization of Ba 5s in the high-energy Cooper minimum region has been investigated using the relativistic-random-phase approximation and the relativistic-random-phase approximation with relaxation. Comparison with recent experiment shows good agreement for the total cross section, but only qualitative agreement for the photoelectron angular distribution asymmetry parameter, β. The disagreement was traced to the omission of photoionization-plus-excitation channels arising from the 4d subshell.

title: Radiative lifetimes of 120 odd-parity levels of neutral Sm

description: <b>Table 1.</b> Radiative lifetimes of 120 odd-parity levels of neutral Sm. <strong>Abstract</strong> Radiative lifetimes of 120 odd-parity levels of neutral samarium, ranging in energy from 17 190 to 33 507 cm<sup>−1</sup>, are measured using the technique of time-resolved laser-induced fluorescence on a slow atomic beam. This work is part of an ongoing study of radiative properties of rare earth neutral atoms, and is motivated by research needs in astrophysics and lighting technology. This set of Sm i lifetimes substantially increases the available published lifetime data, with 49 of the 120 level lifetimes measured for the first time. These data, most of which are accurate to ±5%, will be combined with branching fractions determined from Fourier transform spectroscopy to produce a large set of measured Sm i transition probabilities.

title: Dominant ionization channel of W<sup>43 +</sup> to W<sup>46 +</sup> ions at <em>T<sub>e</sub></em> = 2 keV

description: <b>Table 2.</b> Dominant ionization channel of W<sup>43 +</sup> to W<sup>46 +</sup> ions at <em>T<sub>e</sub></em> = 2 keV. <strong>Abstract</strong> The fractional ion abundance and rates of ionization and recombination of multiple charged tungsten ions in magnetic fusion plasmas are investigated using a collisional radiative model. Using a computer algorithm to generate a set of atomic states to be included in the collisional radiative model, the dominant dielectronic recombination and excitation autoionization channels are determined by a systematic convergence analysis of the level population and ion abundance with respect to the size of the model. The atomic data, such as energy levels and rates of the radiative decay as well as autoionization, are obtained by the <em>ab initio</em> calculation using the Hebrew University Lawrence Livermore Atomic Code. The calculations are carried out in the temperature range of 100 eV–5 keV, and the ratio between the abundances of W<sup>44 +</sup> and W<sup>45 +</sup> ions agrees well with an experimental result obtained without any artificial adjustment of the atomic rates.
