Figure 6
Phonon dispersion in diamond along the (H,0,0) direction measured with Si(844) crystal analysers (R = 2 m) at 11.215 keV and 25 meV energy resolution (open blue circles), compared with literature data (red line). The inset shows the stability of the relative phonon energy versus time. A small drift of ∼1 meV h−1 is observed.
