P. Mazzotta et al., Ionization balance for optically thin plasmas: Rate coefficients for all atoms and ions of the elements H to Ni, ASTR AST SS, 133(3), 1998, pp. 403-409
We present in this paper new and updated calculations of the ionization equ
ilibrium for all the elements from H to Ni. We collected for these elements
all the data available in the literature for the ionization and radiative
plus dielectronic recombination rates, In particular, the dielectronic rate
s have been fitted with a single formula and the related coefficients are t
abulated. Our results are compared with previous works.
