Abstract

In situ x-ray diffraction from laser-shocked crystals provides one means of diagnosing high strain-rate (10⁸ - 10⁹ s^-1) compression/tension waves in solids. Typically the radiation diffracted from the shocked crystals is relatively broadband, consisting of the resonance and intercombination lines of the helium-like ions of medium Z atoms, and their associated lithium-like dielectronic satellites. Deconvolution of this time-dependent x-ray spectrum will yield more detailed information on the strain profiles within the crystal. Preliminary results of a maximum entropy routine are presented.
