【Abstract】 A collisional radiative model based on the spin-orbit-split-arrays was develo ped and used to determine the charge state distributions. The atomic structure c ode of Cowan and the spin-orbit-split-arrays model is used to calculate all t he emission spectra of the different gold species, and a non-local thermodynami c eguilibrium model is coupled to calculate the ion populations and the charge s tate distributions at a given density and temperature. The relationship between a verage charge state and the electron temperature is given.In general, the averag e charge state increases with electron temperature, except between 3800 and 3900 eV. The reason for this unusual region is that the ionization potential increas es much sharply between Au51 and Au52.更多还原
