Anomalous diffraction in crystallographic phase evaluation.
X-ray diffraction patterns from crystals of biological macromolecules contain sufficient information to define atomic structures, but atomic positions are inextricable without having electron-density images. Diffraction measurements provide amplitudes, but the computation of electron density also requires phases for the diffracted waves. The resonance phenomenon known as anomalous scattering of...
متن کاملEstimation of anomalous signal in diffraction data.
It is difficult to judge objectively the amount and resolution limit of the anomalous signal present in diffraction data. While several criteria can be used for this purpose, the usefulness of these indicators varies and depends on factors such as the data redundancy, the accuracy of the estimation of intensities and their uncertainties, and the properties of the anomalously scattering atoms in...
متن کاملAbsorption spectra of AA-stacked graphite
AA-stacked graphite shows strong anisotropy in geometric structures and velocity matrix elements. However, the absorption spectra are isotropic for the polarization vector on the graphene plane. The spectra exhibit one prominent plateau at middle energy and one shoulder structure at lower energy. These structures directly reflect the unique geometric and band structures and provide sufficient i...
متن کاملAnomalous quasiparticle lifetime in graphite: band structure effects.
We report ab initio calculations of quasiparticle lifetimes in graphite, as determined from the imaginary part of the self-energy operator within the GW approximation. The inverse lifetime in the energy range from 0.5 to 3.5 eV above the Fermi level presents significant deviations from the quadratic behavior naively expected from Fermi liquid theory. The deviations are explained in terms of the...
متن کاملRevisit to diffraction anomalous fine structure
The diffraction anomalous fine structure (DAFS) method that is a spectroscopic analysis combined with resonant X-ray diffraction enables the determination of the valence state and local structure of a selected element at a specific crystalline site and/or phase. This method has been improved by using a polycrystalline sample, channel-cut monochromator optics with an undulator synchrotron radiat...
