Figure 5
Inelastic X-ray scattering spectrum of polycrystalline beryllium at 0.44 a.u. momentum transfer (16° scattering angle) as a function of the transferred energy. The incident photon energy was scanned around the fixed analyser energy of 5.93 keV. The intensity is normalized to the monitor signal. The counting time for a single data point at the plasmon peak is 30 s. |
