“…If the zero-density DR data α DR (T ) in Eq. (1) neglects the secondary autoionization (Blaha 1972), this parameterization is sufficient for all isoelectronic sequences N ≥ 6. However, the given parameterization was not flexible enough to provide an adequate fit to the Summers (1974Summers ( & 1979 data for the lower isoelectronic sequences N ≤ 5.…”

We present improved fits to our treatment of suppression of dielectronic recombination at intermediate densities. At low densities, most recombined excited states eventually decay to the ground state, and therefore the total dielectronic recombination rate to all levels is preserved. At intermediate densities, on the other hand, collisions can lead to ionization of higher-lying excited states, thereby suppressing the dielectronic recombination rate. The improved suppression factors presented here, although highly approximate, allow summed recombination rate coefficients to be used to intermediate densities. There have been several technical improvements to our previously presented fits. For H-through B-like ions the activation log densities have been adjusted to better reproduce existing data. For B-, C-, Al-, and Si-like ions secondary autoionization is now included. The treatment of density discontinuity in electron excitations out of ground state H-, He-, and Ne-like ions has been improved. These refined dielectronic recombination suppression factors are used in the most recent version of the plasma arXiv:1808.07365v1 [physics.atom-ph]
