    • Certain behaviors of spin and charge motions have been observed in 1D polyacetylene, as summarized by Heeger et al. in Rev. Mod. Phys. 60, 781 (1988). However, those behaviors are driven by electron-phonon interaction, and are different from the correlation driven spin-charge separation discussed here.

    • It was later found that this holds true for low photon energies such as (Formula presented) (private communication with T. Mizokawa). If we consider the fact that Cu and O are mostly in their (Formula presented) and (Formula presented) states, their cross-section ratio becomes approximately 10 For the calculated atomic cross sections, refer to J.-J.

    • It was initially pointed out by Sawatzky et al. [ Phys. Rev. B 20, 1546 (1979)] that the calculated atomic cross section should be multiplied by 3 to reproduce the whole valence-band spectra of the (Formula presented) transition-metal oxides for Mg (Formula presented) It was later found that this holds true for low photon energies such as (Formula presented) (private communication with T.
