Transverse dynamics of water across the melting point: A parallel neutron and x-ray inelastic scattering study

Journal Article Cunsolo, A ; Kodituwakku, C ; Bencivenga, F ; ... - Physical Review. B, Condensed Matter and Materials Physics

Joint inelastic neutron and x-ray scattering measurements have been performed on heavy water across the melting point. The spectra bear clear evidence of low- and high-frequency inelastic shoulders related to transverse and longitudinal modes, respectively. Upon increasing the momentum transfer, the spectral shape evolves from a viscoelastic regime, where the low-frequency mode is clearly over-damped, toward an elastic one where its propagation becomes instead allowed. The crossover between the two regimes occurs whenever both the characteristic frequency and the linewidth of the low-frequency mode match the inverse of the structural relaxation time. Furthermore, we observe that the frequency of themore »« less

Transverse dynamics of water across the melting: a parallel Neutron and X Ray Inelastic Scattering study

Journal Article Cunsolo, Alessandro ; Koditwakku, Nalaka ; Frontzek, Matthias D. ; ... - Physical Review B

Joint Inelastic Neutron and X Ray Scattering (INS and IXS) measurements have been performed on heavy water across the melting point. The spectra bear clear evidence on a low and a high frequency inelastic shoulders related to a transverse and a longitudinal mode respectively. Upon increasing the momentum transfer, the spectral shape evolves from a viscoelastic regime, where the low frequency mode is clearly overdamped, towards an elastic region where its propagation becomes allowed. The crossover between the two regimes occurs whenever both the position and the width of the low frequency mode match the inverse of the structural relaxationmore »« less

Structure and dynamics of cadmium telluride studied by x-ray and inelastic neutron scattering

Journal Article Niedziela, J. L., E-mail: niedzielajl@ornl.gov ; Stone, M. B., E-mail: stonemb@ornl.gov - Applied Physics Letters

We present a combined study of density functional theory, x-ray diffraction, and inelastic neutron scattering examining the temperature dependent structure and lattice dynamics of commercially available cadmium telluride. A subtle change in the structure is evinced near 80 K, which manifests also in the measured phonon density of states. There is no change to the long-range ordered structure. The implications of the change in relation to structural defects are discussed.

A compact point focusing spatial filter for x-ray fluorescence and inelastic x-ray scattering studies

Journal Article Behne, E A ; Feng, Yejun ; Seidler, G T - Review of Scientific Instruments

Appropriately selected absorbers combined with spatial filters are frequently used as x-ray low-pass filters in inelastic x-ray scattering studies and x-ray fluorescence spectroscopies. We describe here a compact point focusing spatial filter with a large collection solid angle and excellent rejection of fluorescence from an absorber when used as an x-ray low pass filter. We expect this instrument to have regular application in x-ray microscopies where momentum resolution is irrelevant, such as x-ray fluorescence holography or fluorescence-mode x-ray absorption fine structure measurements using micro-focused beams. As an additional application, we demonstrate that the filter can also be used as themore »« less
