摘要：

The temporal evolution of plasmas produced by high-contrast picosecond laser irradiation of solid targets consisting of fluorine salts of different mean atomic number was studied using time-resolved x-ray spectroscopy. The main spectral features including fluorine resonance lines and continuum emission at the peak of emissions were compared to hydrodynamic and atomic physics simulations. The temporal evolution of the intensity of both He-like and H-like main resonance lines exhibited a faster decay for higher-Z targets as a result of a faster cooling of the plasma.
