scattering

 [skat´er-ing]
a change in the direction of motion of a photon or subatomic particle as the result of a collision or interaction.

scattering

Etymology: ME, scateren
a change in the direction of photons caused by the interaction between photons and matter. In coherent scattering, an incident photon interacts with matter and excites an atom, causing it to vibrate. The vibration causes the photon to scatter. Also called Thompson scattering, unmodified scattering. In Compton scattering an incident photon interacts with an orbital electron, transferring some of its energy to that electron. The electron is ejected, and the photon is scattered.

The analytical theory of the multiple scattering of light in heterogeneous media is based on the vector form of the Foldy-Lax equation.
Now, regardless of their respective merits and limitations, those formalisms have two major drawbacks which made them inappropriate for our study: (a) they require the implementation of an explicit and time-consuming numerical procedure to evaluate the configuration average optical parameters of the random heterogeneous media under study; (b) they provide resolutions of the multiple scattering equation of light on a fixed N-particle system dispersed in a continuous medium, typically from only 10 to 100, which limits the corroboration with experimental data generated from macroscopic films.
Section 2 presents the features of the scattering center on the streamlined smooth surface through the analysis of scattering characteristics.
For target with streamlined smooth surface, the change patterns of sliding scattering centers in amplitude and location are determined essentially by its particular scattering characteristics.
In the classification algorithms mentioned above, scattering mechanism identification plays an important role.
In [9], the scattering mechanism identification is achieved by using the dominance of the backscattering power obtained by Freeman decomposition.
8220;Our company brings closure to mourning families by conducting a dignified ash scattering memorial, surrounded by the spiritual red rocks mountains of Sedona, AZ,” John says.
As increasing number of people are using ash scattering services together with Online Memorials and networking sites, blogs and Facebook, as ways of showing love and respect for the deceased.

In particular, it appears that a series of publications (2) tend to systematically dissociate the origins of dependent scattering from multiple scattering phenomena even in white paint films.
Because the scattering behavior of nano-sized particles and domains (1 to 100 nm in size) trend toward small angles, these can be differentiated from scattering that occurs from atoms and interatomic distances (less than 1 nm), which produce relatively wide angles of scatter.
The measurement of absorption and scattering in a turbid environment is an important problem.
