Abstract
Silicon tar ets irradiated at large incidence angle (60 degrees) with ultrashort (120 fs) P-polarized laser pulses at high intensities (appr oximate to 10(16) W cm(-2)) display significantly broadened K-shell x- ray line emission. To analyze the spectra we have calculated Stark-bro adened 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 characterist ic of near solid densities and that there is an unusually high contrib ution from high-order satellite transitions; this could be due to a co mbination of high-density and transient effects.
