ABSTRACT

  This beamline provides Inelastic X-ray Scattering (IXS) and Nuclear Resonant Scattering (NRS) measurements, utilizing hard X-ray of > 14 keV.
  1) In the IXS hutches, dynamic structure factor, S (Q, ω), with ∼ meV energy resolution and > 1 nm-1 momentum transfers can be obtained using the IXS spectrometer [Baron, et al, J. of Phys. Chem. Solids 61, (2000) 461]. This method can be a powerful tool for investigating atomic dynamics of disordered materials (liquids and glasses) and small samples, where neutron scattering has severe limitations. In particular, IXS allows access to ∼ 1 nm-1 momentum transfers and large (< 0.5 eV) energy transfers with ∼ meV resolution. Meanwhile the beam size, < ∼100 µm diameter, makes small samples (< 0.01 mm3) readily accessible.
  2) In the NRS hutches, the following methods are primally available; Atomic or molecular dynamics using nuclear resonant inelastic scattering in meV region (NRVS/NIS) and quasi-elastic scattering (TDI, Rayleigh Scattering) in neV-µeV region, Hyperfine/Mössbauer spectroscopy (NFS, EDMS). Mössbauer spectroscopy in Synchrotron facility is especially advantageous for measurements in extreme conditions, in diffraction condition, and in cases where no Mössbauer source is readily available.
