Abstract : Silicon targets irradiated at large incidence angle (60°) with ultrashort (120 fs) P-polarized laser pulses at high intensities (≊1016 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 Heα resonance line and its satellite transitions in Li-, Be-, and B-like ions with spectator electrons in theL 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.
