Dielectronic recombination (DR) and radiative recombination (RR) data for
oxygen-like ions forming fluorine-like ions have been calculated as part
of the assembly of a level-resolved
DR and RR database necessary for modelling of dynamic
finite-density plasmas (Badnell et al. [CITE]). Total DR and RR rate
coefficients for
F+ to
Zn22+ are presented and the results discussed. By comparison between
perturbative and R-matrix results, we find that RR/DR interference effects
are negligible even for the lowest-charged F+ member. We also find
that the low-temperature DR
(no change in the principal quantum number of the core electrons)
does not scale smoothly with
nuclear charge Z due to resonances straddling the ionization limit,
thereby making explicit calculations for each ion necessary.
These RR and DR data are suitable
for modelling of solar and cosmic plasmas under conditions of
collisional ionization equilibrium, photoionization equilibrium, and
non-equilibrium
ionization.
