We describe a novel proposed experimental method for X-ray diagnostics of terawatt class laser - solid interaction. Here resonant bound-bound electron transitions in ions give rise to a diffraction pattern that can be used to derive the distribution of ions. The transition energy of a specific transition (e.g. K alpha) is sensible to the degree of ionization, so that an intense mono energetic X-ray beam (XFEL) can be used to select a given in species. The feasibility is studied using quantitative simulations and the great potentials and unique possibilities of this method are highlighted.
