Figure 9
Extracted Si L and O K edges of SiO2 for different q. The near-edge region is shown in the top part of the inset where the pre-edge is shifted to zero to compensate for the offset owing to the O LI edge. The spectra are normalized to the area between 100 and 120 eV. The bottom part of the inset shows q-dependent calculations of the Si LII,III edges employing an ab initio NRIXS approach based on the StoBe-deMon code. Corresponding features of experiment and theory are indicated by arrows. This figure is in color in the electronic version of this paper. |
