Figure 6
(a) Fluorescence spectra of an Fe alloy containing 1 at% Mn for different excitation energies in the vicinity of the Mn K-edge (6.539 eV) as indicated. (b) Raw fluorescence EXAFS at the Mn K-edge of the Fe base alloy within ∼1 h of total integration time. The data are extracted from the data of (a) using the region of interest (ROI) indicated by the vertical dotted lines. The inset shows the magnitude of the Fourier transform of the k3-weighted EXAFS fine structure. |
