Popis: |
Lifetime-broadening-suppressed X-ray absorption near-edge structures (LBS-XANES) spectra, where the resolution is not restricted by core-hole lifetime widths, have been measured at the Cu K-edge on the prototypical high- T c La 2− x Sr x CuO 4 ( x =0, 0.15, and 0.29) single crystals. Thanks to improved resolution, 1s-3d excitation bands have been clearly separated from the main transitions and their concentration as well as polarization dependences are examined. |
