Abstract
In the past few years new calculations of the ionization and recombination rates have been published. The new Fe ionization equilibrium for these new rates is available for a Maxwellian distribution. Therefore the updated Fe ionization equilibrium for the non-thermal κ-distribution with an enhanced number of particles in the high-energy tail is presented. Results for the various deviations from a Maxwellian distribution are given in tabular form and these are compared with previous ones. A method for the determination of an energy distribution different from the Maxwellian one is suggested.
