We present new calculations and analytic ts to the rates of radiative recombination towards H-like, He-like, Li-like and Na-like ions of all elements from H through Zn (Z = 30). The ts are valid over a wide range of temperature, from 3 K to 10 9 K.
We present a complete set of analytic ts to the non-relativistic photoionization cross sections for the ground states of atoms and ions of elements from H through Si, and S, Ar, Ca, and Fe. Near the ionization thresholds, the ts are based on the Opacity Project theoretical cross sections interpolated and smoothed over resonances. At higher energies, the ts… (More)
