On the importance of satellite lines to the He-like K ALPHA complex and the G ratio for calcium, iron, and nickel
J. Oelgoetz, C. J. Fontes, H. L. Zhang +2
New, more detailed calculations of the emission spectra of the He-like K ALPHA complex of calcium, iron and nickel have been carried out using data from both distorted-wave and R-m…
A study of the breakdown of the quasi-static approximation at high densities and its effect on the helium-like K ALPHA complex of nickel, iron, and calcium
Justin Oelgoetz, Christopher J. Fontes, Hong Lin Zhang +1
The General Spectral Modeling (GSM) code employs the quasi-static approximation, a standard, low-density methodology that assumes the ionization balance is separable from a determi…
High-temperature behaviour of the helium-like K ALPHA G ratio: the effect of improved recombination rate coefficients for calcium, iron, and nickel
J. Oelgoetz, C. J. Fontes, H. L. Zhang +3
It is shown that above the temperature of maximum abundance, recombination rates into the excited states of He-like ions that are calculated using earlier, more approximate methods…
Resolution and accuracy of resonances in R-matrix cross sections
Franck Delahaye, Sultana N. Nahar, Anil K Pradhan +1
We investigate the effect of resonances in photoionization and recombination cross sections computed using the R-matrix method. Photoionization and recombination rates derived from…
