Figure 3
(a) Probed volume in reciprocal space with the Ewald spheres of three different X-ray energies. The volume probed by the momentum transfer Q using X-rays of a finite energy band is indicated by the hatched box. The diffracted intensity spots recorded on the detector represent the values at the corresponding positions indicated in the same colors in reciprocal space. (b) Diffraction profile of the NiO thin film corresponding to the scheme illustrated in (a) measured with three individual pulses. Qz profiles of the diffraction pattern are plotted with the inset showing the captured images on the detector. The dotted blue line is the result of the fit with a fitting error in the peak position that is translated into ∼1 eV in energy. |
