主 题:extreme ultraviolet spectra laser-produced plasmas collisional-radiative model cadmium
摘 要:In order to provide detailed information about Cd structure and gain more insight regarding ionization degrees and types of transition,as well as the understanding of the temporal evolution behavior of laser produced Cd plasmas,extreme ultraviolet spectra of laser-produced cadmium(Cd)plasmas have been measured in the 8.4-12 nm region using spatiotemporally resolved laser-produced plasma spectroscopy *** features were analyzed by the Hartree-Fock(HF)method with relativistic correlations(HFR)using the Cowan *** results showed that the 4p-5s resonance transition arrays from Cd^9+to Cd^13+merged to form intense lines in this spectral region.A number of new spectral features from Cd^9+and Cd^10+ions are reported in this *** on the assumption of a normalized Boltzmann distribution among the excited states associated with a steady-state collisional-radiative model,the plasma parameters were obtained by comparing the experimental and simulated *** a result,we succeeded in reproducing the synthetic spectra for different time delays,which yielded good agreement with the *** temporal evolution behaviors of electron temperature and electron density of plasma were also analyzed.
