摘要
Experimental and theoretical analyses are reported for the spatiotemporal evolution of extreme ultravio-let spectra in laser-produced silver (Ag) plasmas. The time-resolved spectra were acquired 1.5 mm from the target surface. The 4p and 4d excitations of Ag7 + -Ag13 + ions were calculated with the aid of multi-configuration Hartree-Fock calculations. The spectral line distributions of transitions in the dominant 4p and 4d excitation configurations and their variations with the degree of ionization were analyzed. Com-plex spectral structures were accurately revealed based on the assumption of a normalized Boltzmann distribution among the excited states and a steady-state collision-radiative model. Experimental peak ori-gins were identified by comparing experimental and simulated spectra. These results will provide data for energy-level structures of highly-charged ions of middle-and high-Z elements and their radiative characteristics in plasmas.(c) 2023 Published by Elsevier Ltd.
