High-energy measurements: S(q) obtained at (a) 25 keV, (b) 46 keV, (c) 48.480 keV and (d) 54 keV. Si[311] monochromator crystals have been used for (a), the third-harmonic reflection Si[933] has been used for (c) and (d), and Si[511] crystals were employed for (b). The arrow indicates the maximum momentum transferred reachable using Eu L-edge energy. |
