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…

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…
