The quasisteady structure of the corona of a laser‐irradiated pellet is completely determined for arbitrary Zi (ion charge number) and rc/ra (ratio of critical and ablation radii), and for heat‐flux saturation factor f above approximately 0.04 . The ion‐to‐electron temperature ratio at rc grows sensibly with Zi; all other quantities depend weakly and nonmonotonically on Zi. For rc/ra close to unity, and all Zi of interest (Zi 1.2 roughly, the mass ablation rate is C(Zi)[(mi/kZi)7 u/2 Kr11aP5a]1/6, independent of ρc and f, and barely dependent on Zi(mi is ion mass; k, Boltzmann’s consta...
