(a) Fe and ELNES collected under 15 different diffraction conditions. The spectra are normalized so that the peak maxima of Fe ELNES exhibit the same height. The total exposure time per spectrum was . The energy resolution was 1.0 eV. (b) The DPs corresponding to nos. 1 and 15 spectra in (a). The thick (thin) vertical lines denote the positions of the set of 400 (800) Kikuchi lines. We set a beam convergence semiangle of 4.6 mrad, a collection semiangle of 7.5 mrad, and an EELS entrance aperture off-axis shift of 1.5 .
Comparison between the theoretical and experimental site-selectivity, with respect to the incident beam orientation, which is represented by a dimensionless parameter , where is the extinction distance of the 400 beam. We set the same aperture conditions as in the experiment.
Comparison between theoretical and experimental site-specific ELNES. The energy resolution in the experimental spectra was 1.0 eV. The theoretical spectra were obtained by convoluting a 0.6 eV Lorenz function with the discrete transition probabilities so as to show the fine structures clearly.
Configuration analysis of many-electron wave functions corresponding to the final states of peaks A and B in the edge. Because the basis set of the Slater determinants are orthonormal, using an eigenvector , an electron configuration ’s composition is simply given by .
