Abstract
Dielectronic recombination (DR) and radiative recombination (RR) data
for carbon-like ions
forming nitrogen-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. 2003).
Total DR and RR rate coefficients are presented and the results
discussed for N
+ to Zn
24+,
as well as Kr
30+, Mo
36+, Cd
42+, and Xe
48+.
We find that the
(no change in the principal quantum
number of the core electron)
low-temperature DR does not scale smoothly with nuclear charge
Z
due to resonances straddling
the ionization limit, thereby making explicit calculations for each
ion necessary.
The 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.
Key words: atomic data -- atomic processes -- plasmas
