Evaluation of the energy resolution at the Mn K-edge. The experimental values are obtained from the FWHM of the pre-edge structure of a KMnO4 powder sample. The FWHM of the pre-peak is ∼2 eV for a slit aperture of 0.6 mm. The comparison of the calculated and measured instrumental energy resolution as a function of the slit aperture is shown in the insert for the normal source (continuous line) and large source (dotted line). The measured points are obtained by deconvolution from core-hole and 3d-band width contributions (∼1.5 eV). |
