REDUCED TIME-DEPENDENT COLLISIONAL-RADIATIVE MODEL

摘要

The Quasi-Static Hypothesis (neglecting relaxation time among the populations of the excited levels of a same charge state) already allows a dramatic simplification of the Collisional-Radiative ionization models, as only the populations of the ground states need to be followed. We go further with this Reduced Collisional-Radiative model, by following only the mean charge and computing its time evolution without explicitly following the population of any charge state.
