The First-principle Theory For The Charge State Distribution Of Au Plasma And The Effect Of Amount Of Ions On Its Distribution

Using the extended relativistic multi-configuration Dirac-Fock theory and the general-purpose relativistic atomic structure program 2(GRASP2) with quantum electrodynamical effect(QED) and breit correction, we have calculated the energy level structures, transition wavelengths, transition probabilities, oscillator strengths, energy level lifetimes, level widths and ionic average lifetimes of As-like Au⁴⁶⁺, Ge-like Au⁴⁷⁺ and Fe-like Au⁵³⁺.Our research group has already obtained the charge state distribution and the averaged ionization state of 5-ion system (i.e.Au⁴⁸⁺～Au⁵²⁺).It is found that more highly charged ions could be able to be neglected, however, less highly charged ions are rather important to the whole system.Therefore, we extend 5-ion system to 7-ion(i.e. Au⁴⁷⁺～Au⁵³⁺) and 8-ion system(i.e. Au⁴⁶⁺～Au⁵³⁺).Using consecutive-irreversible ionization reaction, we have calculated the charge state distributions and the averaged ionization states of the two systems above. Furthermore, under the condition of electron temperature T_e=400～2000eV and electron density D_e=10¹⁸～10²⁶cm^-3, we have calculated the charge state distribution and averaged ionization state of 7-ion system with consecutive-reversible ionization-recombination reaction. In addition, the analytic functions between the ionic abundance ratio and electron temperature have been established at D_c=10²³Ccm^-3, T_e=500～600eV and D_e=10¹⁸cm^-3, T_e=1400～1600eV, and the analytic functions between the ionic abundance ratio and electron density have also been obtained at T_e=550eV, D_e=10²³ï½ž10²⁶cm^-3.
