Popis:	The blast wave theory coupled with ionization described by the Saha equations and the charge conservation equation, are used to calculate the time‐dependent, spatial distribution of the number densities of the different species of a plasma formed on a carbon surface. The temporal behavior of the normalized intensity profiles of the C i (247.8 nm) and C ii (251.1 nm) lines and the Stark shifts of the C i (247.8 nm) line from 0.1 to 0.4 μs are obtained. Good agreement is found between theoretical and experimental time‐dependent, normalized, line intensity profiles and Stark shift profiles.
