Introduction to diffuse scattering and data collection

2023
A long-standing goal in X-ray crystallography has been to extract information about the collective motions of proteins from diffuse scattering: the weak, textured signal that is found in the background of diffraction images. In the past few years, the field of macromolecular diffuse scattering has seen dramatic progress, and many of the past challenges

Multiple scattering model for collections of bianisotropic acoustic scatterers

The Journal of the Acoustical Society of America, 2023
The magnitude of an acoustic point source is traditionally described as monopole, dipole, or higher-order multipole source strengths. The polarizability tensor, commonly used in electromagnetics, can be used to describe the scattering from an acoustically small heterogeneity in a background medium as monopole, dipole, and higher order multipoles due to

Squeezing in collective Raman scattering

Physics Letters A, 1988
Abstract The generation of a squeezed state via the collective Raman scattering in an intense external field is discussed. It is shown that squeezing is present only in the mixture of two sidebands of the Rayleigh line while it is absent for the Stokes line.

Novel small-angle collective Thomson scattering system

Applied Optics, 1985
A Thomson scattering opticals system is described with the following characteristics: (1) it allows scattering angles down to 1 mrad before collection optics interfere with beam dumping; (2) it gives excellent k resolution for angles of > or approximately 1.5 mrad; (3) it collects light from a scattering volume which can be variably positioned without ...

Modulational instability arising from collective Rayleigh scattering

Physical Review E, 2003
It is shown that under certain conditions a collection of dielectric Rayleigh particles suspended in a viscous medium and enclosed in a bidirectional ring cavity pumped by a strong laser field can produce a new modulational instability transverse to the wave-propagation direction.

Collective Theory for Surface Enhanced Raman Scattering

Physical Review Letters, 1996
We present an implementation of Maxwell's equations on adaptive meshes in order to study interaction of light with metal surfaces. For the first time it is possible to handle surfaces consisting of complex particles close enough to interact strongly. A fully retarded implementation allows treatment of large particles as well as small. By way of example

Collective Thomson scattering at W7-AS

Plasma Physics and Controlled Fusion, 1997
Collective Thomson scattering (CTS) of electromagnetic radiation from thermal plasma fluctuations in principle allows the velocity distribution of plasma ions and its composition in the plasma to be measured. The use of powerful microwave radiation from gyrotrons opens new perspectives for the application of CTS, which is considered to be a promising ...

Collective quantum scattering in plasma

Astroparticle Physics, 1996
Abstract Collective quantum plasma effects in scattering of photons on electrons are derived. The generalization of Klein-Nishina scattering is obtained. The dependence of scattering on the collective plasma parameter and the ratio of the photon energy to the electron thermal energy is investigated.
