incoherent scattering

incoherent scattering

[‚in·kō′hir·ənt ′skad·ə·riŋ]
(physics)
Scattering of particles or photons in which the scattering elements act independently of one another, so that there are no definite phase relationships among the different parts of the scattered beam.

Among specific topics are small-angle neutron scattering (SANS), neutron imaging, calculating real space parameters and ab initio models from isotropic elastic SANS patterns, the soft matter sample environment for SANS and neutron reflectometry, dynamics of polymers, protein dynamics studied by neutron incoherent scattering, and pulsed neutron sources and facilities.
Fairly accurate cross section values for coherent and incoherent scattering are available (Hubbell et.
Note that the incoherent scattering contributions from the hybrid components were subtracted from the SANS profiles prior to the following Porod Law analysis of the experimental data.
ellipsoids] was discussed above and B is a constant representing the Q-independent background mostly due to incoherent scattering from hydrogen.
Finally, the q-independent background incoherent scattering, primarily because of hydrogen atoms, was removed by scaling the scattering from a pure protonated polymer sample by the proton density in the scattering volume.
These reasons include higher order reflections from the monochromator and/or analyzer, incoherent scattering from the monochromator or analyzer, and scattering from materials in the beam in addition to the sample.
The incoherent scattering gives rise to a smooth background, which is angle independent at large angles.
In this picture, some UCN are spin flipped upon reflection due to incoherent scattering from para/ferro-magnetic centers on the material surface.
In a backward direction [Theta] [greater than] 0 the enhancement decreases rapidly as [Theta] increases and the intensity I([Theta]) reaches the incoherent scattering value [I.
