We present a review of our fully relativistic approach to calculating atomic data for highly
charged ions, highlighting a research effort that spans twenty years. Detailed discussions of …

A programme is outlined for the assembly of a comprehensive dielectronic recombination
database within the generalized collisional–radiative (GCR) framework. It is valid for …
