Figure 6
(a) First-derivative profile of the X-ray absorption spectrum, dμt/dE, of the NPD anvils. Ticks near the profile indicate peaks due to hkl Bragg reflection from the anvils. (b) and (c) Solid circles in the upper panels denote the enlarged plots of the absorption spectrum using the NPD anvils at around (b) E311 = 6.952 keV and (c) E422 = 8.514 keV. The solid lines represent the fitted curves based on the Victoreen equation (see text). The open circles in the lower panels correspond to the difference between the experimental data and the fitted curves. The vertical lines indicate the position of Ehkl where hkl reflection occurs. This figure will appear in color in the online version of the paper. |
