The agreement between experimental results and theoretical predictions is
improved for the temporal dynamics of the gain coefficient on the 3 to 2
transition of the C VI ion at 182 A. It is shown that nj kinetics improves
the description of radiative cleaning of the n=2 level in a partially
reabsorbed, expanding plasma, surprisingly increasing the degree of frozen
ionization. A detailed description of radiative trapping on the n=2,3 levels
is included in the model in the form of the net radiative bracket, calculated
through an exact solution of the radiation transfer problem. The accurate
treatment of radiative transport is found to convincingly verify the Sobolev
formulation of the escape factor.
