FIG. 4.
ΔSCF XAS rectified by the many-electron matrix formalism for TiO2 (a) and CrO2 (b). For comparison, the spectra produced by the one-body FCH formalism are denoted as 1p, and experimental (EXP) and BSE spectra as in Fig. 1 are also added with the first peaks aligned. (c) and (d) show the higher-order intensity contributions (in log scale) that do not exceed 0.004 in both cases.
