Figure 7
(a) Fermi-edge profile of a gold sample obtained using Si(444) CCM at the photon energy 7.94 keV. Open circles indicate the experimental data and the solid line represents the fitting result of them. (b) Total energy bandwidths as a function of the photon energy and the index of the DCCM crystal. The solid circles indicate those obtained by Fermi-edge measurements of a gold sample, and the solid lines show the calculated values. The dotted lines are the theoretical energy bandwidths of the incident X-rays after DCCMs. |
