We examine the effect of core-hole lifetime on the spectral weight of resonant inelastic X-ray scattering (RIXS) in hole-doped cuprates. We calculate the spectral weight by using the exact diagonalization technique for a 4 × 4 doped Hubbard lattice and find that the spin-flip channel detecting single-magnon excitation is less sensitive to the core-hole lifetime while in the non-spin-flip channel the spectral weight is strongly dependent on the lifetime. In the latter, charge and two-magnon excitations predominately contribute to RIXS for short and long core-hole lifetimes, respectively. For a realistic value of the core-hole lifetime in cuprates, both the charge and two-magnon excitations are expected to contribute to the non-spin-flip channel in RIXS when the incident-photon energy is tuned to the main peak of X-ray absorption spectrum.

Anomalous small-angle X-ray scattering with two marker elements was applied to the structural analysis of poly(4-vinylphenol rubidium salt)-block-poly(4-bromostyrene) (RbPVPh-b-PBrS) micelles, where Br and Rb were the markers for the hydrophobic core and the hydrated corona, respectively. By using two different markers for the hydrophobic core and the hydrated corona, the form factors of the core and corona were extracted separately from the scattering profile of the whole RbPVPh-b-PBrS micelles. The form factor of the hydrophobic core (the spatial distribution of Br) revealed that the core was regarded as a solid sphere with a smooth surface and a radius of 47 nm. Conversely, the form factor of the spatial distribution of Rb+indicated that the shell of the RbPVPh-b-PBrS micelles was 15 nm thick.

The crystallographic and structural characteristics of GaN tripods and hexapods grown onc-plane sapphire substrates were investigated using synchrotron X-ray scattering and microscopic analysis. The core structure of a GaN hexapod is revealed to be in the zincblende phase with an inversion domain, and a refined crystallographic analysis of tripods and hexapods with synchrotron X-ray scattering shows the existence of the zincblende phase in wurtzite-based protruding nanorods. The atomistic model combined with this crystallographic analysis reveals that the core size of a hexapod is much smaller than the diameters of the protruding nanorods. This refined structural analysis can be utilized in tailoring the opto-electronic characteristics of GaN multipods.

AbstractIn an attempt to treat independently the contribution of the inner and outer electrons of the different atoms to the total x-ray scattering the selected-electron shell (SES) method was developped, representing the atomic scattering factor by a three- or four-term Gaussian polynomial and associating the Gaussian constants with the electron shells of the atom.For most atoms however and contrary to the hypothesis no simple relation can be made.Therefore, the atom is considered as a non-rigid body, built up from two distinguishable terms: the core and the outer electrons. The core is assumed to form a closed, spherically symmetric shell, making an overall description of its scattering power by a one-term Gaussian function, within some limits in reciprocal space, quite possible.
