Figure 2
XANES spectra observed by using the Si(111) bent crystal polychromator (blue) and the Si(220) double-crystal monochromator (red) for (a) Co foil at the Co K-edge and (b) Cu foil at the Cu K-edge. Accumulated widths are shown in the figure. Absorption-edge positions of the Co K-, Eu LII- and LI-edges measured at a fixed optical configuration are shown in (c). |
