Figure 8
Normalized X-NCD spectral differences (σL − σR) recorded at the iodine (a) LIII-edge and (b) LII-edge using an α-LiIO3 single crystal aligned so that the optical axis was collinear with the incident X-ray beam. The polarization-averaged XANES spectra are also displayed for reference. Note the striking similarity in the morphology of the two X-NCD spectra which have the same sign. |
