Silicon Satellite Spectra from Laser-Imploded Microballoons

Abstract

The dielectronic satellite spectral lines, on the long-wavelength side of the hydrogenic Si XIV Lyman-$\alpha$ line, have been observed in the space-resolved spectra from laser-imploded glass microballoons. In the electron density range 1×${10}^{22}$ to 2×${10}^{23}$ ${\mathrm{cm}}^{-3\mathrm{}}$, the intensities of the Si XIII $2s2p{}_{}{}^3{}_{}{}^{}P-1s2s{}_{}{}^3{}_{}{}^{}S$ and $2p^2{}_{}{}^3{}_{}{}^{}P-1s2p{}_{}{}^3{}_{}{}^{}P$ satellite lines increase with density in agreement with numerical modeling. These satellite lines are a promising density diagnostic for the imploded glass plasma.
