Results of fitting measured data at 973 K and pO2 = 150 Torr. (a) Combined fits (solid lines) of measured (open diamonds and dashed lines) non-resonant and resonant CTRs. Only the data points used for fitting are shown. Low-intensity regions and Bragg-peak regions have been omitted. Curves are offset for clarity. The minimized error is indicated. (b) Computed CTRs from RAXR results (solid lines) and measured non-resonant and resonant CTRs (dashed lines). Circles indicate the Li positions where intensities Imeas(Li, ENR, ER) were fitted. (c) Determined electron-density profiles from fits of RAXR data (solid line; Fig. 7) and combined fits (dotted line; Fig. 8a).
