摘要：

Silicon tar ets irradiated at large incidence angle (60 degrees) with ultrashort (120 fs) P-polarized laser pulses at high intensities (approximate to 10(16) W cm(-2)) display significantly broadened K-shell x-ray line emission. To analyze the spectra we have calculated Stark-broadened line profiles for the He-alpha resonance line and its satellite transitions in Li-, Be-, and B-like ions with spectator electrons in the L and M shells. Results indicate that the emission is characteristic of near solid densities and that there is an unusually high contribution from high-order satellite transitions; this could be due to a combination of high-density and transient effects.
