Spectrum Analysis and Level Lifetimes of Au48+ in Au Laser Plasma
The results of inertia confinement fusion (ICF) experiment indicate that the spectra of laser Au plasma contains the transitions of 3d4p,3d4f and 3p5d of Au48+.Based on 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,the transition wavelengths,level lifetimes and level widths of Au48+ have been calculated.The transitions mentioned above have been considered in the calculation.The wavelengths obtained are in good agreement with the experimental data available.The relationship between the level lifetimes and the level widths satisfies with the,Heisenberg uncertainty principle.The results provide reference valuable for average ionic lifetime,charge state distribution and average ionization degree of Au plasma.
