We present first experimental results of the extension of X-ray Magnetic Circular Dichroism (X-MCD) to Small Angle X-ray Scattering (SAXS). The purpose of this study is to determine size distributions and correlations lengths in the nanometer range of magnetic precipitates in granular systems. Magnetic scattering curves obtained with a GdFe system at the Gd La edge are compared with reference m...

Numerous neutron scattering studies of bio-molecular dynamics employ a qualitative analysis of elastic scattering data and atomic mean square displacements. We provide a new quantitative approach showing that the intensity at zero energy exchange can be a rich source of information of bio-structural fluctuations on a pico- to nano-second time scale. Elastic intensity scans performed either as a...

Emphasizing the contribution of Professor Roger A Cowley, FRS to the Theory of Raman Scattering from crystals, the development of the Theory of Raman Scattering since 1928 has been briefly discussed. Some experimental studies of Strontium Titanate using Inelastic Neutron Scattering, Raman Scattering, Electro-paramagnetic resonance measurement and X-ray & Gamma Ray techniques has been briefly di...

To ascertain a direct relationship between the light scattering intensity and the particle scattering the light, thin (6-20 micrometers) sections were cut from frozen human cataracts. Freezing for 15 min (-10 C) and then thawing had no effect on the clarity or light scattering properties of nuclear cataracts. Cortical cataracts treated in the same manner appeared to be much clearer than they we...

The study of this paper focuses on the power angle spectrum (PAS) of the satellite communication downlink in rain environment at millimeter-wave bands. The two-dimension angle distribution expression of the incoherent intensity of the ground receiving antenna in rain is deduced in detail. The coherent intensity is discussed according to the first-order multiple scattering approximation theory. ...

We report a dramatic change in the intensity of a Raman mode with applied magnetic field, displaying a gigantic magneto-optical effect. Using the nonmagnetic layered material MoS2 as a prototype system, we demonstrate that the application of a magnetic field perpendicular to the layers produces a dramatic change in intensity for the out-of-plane vibrations of S atoms, but no change for the in-p...

– We describe a self calibrating optical technique that allows to perform absolute measurements of scattering cross sections for the light scattered at extremely small angles. Very good performances are obtained by using a very simple optical layout similar to that used for the schlieren method, a technique traditionally used for mapping local refraction index changes. The scattered intensity d...

Based on full-wave electromagnetic theory, we derive the zero-forward and zero-backward scattering conditions for radially anisotropic spheres within the quasi-static limit. We find that the near-field intensity can be tuned dramatically through the adjustment of the radial anisotropy, while the far-field light scattering diagrams are similar under the zero-forward or zero-backward scattering c...

The NLSE soliton scattering by impurities is considered in the framework of the one-dimensional model. The scattering intensity is characterized by the reflection coefficient. The reflection coefficient of the soliton is calculated in the Born approximation of the perturbation theory for the following cases: (i) and isolated impurity, (ii) two point impurities, and (iii) a regular or random sys...

A novel intracavity laser diagnostic has been developed to perform quantitative two-dimensional imaging of major species and temperature by using spontaneous Raman scattering and Rayleigh scattering in a turbulent flame. A flash-lamp-pumped dye laser cavity is modified to include sheet-forming optics and 100% reflecting end mirrors. In a comparison of this system with a laser configuration with...
