WebDec 16, 2016 · Incoherent scattering, which corresponds to the interference of an outgoing wavefunction with itself, only contains information about a single scattering unit. There are several origins of incoherent scattering: In neutron-nucleus scattering if the deviation arises from the dependence of the nuclear-spin operator, it is the spin-incoherency. the points guy offers

"WebApr 23, 2016 · Incoherent inelastic scattering can be applied to isolated hydrogens—where the protons can be modelled as in an isolated potential well formed by the surrounding atoms. At higher concentrations, the effect of H–H interactions and the role of hydrogen vibrational density of states are described. Ab initio theory becomes important in this case.

WebIn the case of light, incoherent scattering is called “Rayleigh” scattering when it is elastic. It is a common process that makes us see objects with our eyes, which detect light scattered by these objects. Thus leaves appear green as chlorophyll pigments scatter green light, while it absorbs blue and red lights and is transparent for green light. Webof Compton scattering is given by equation (4), is called the incoherent scattering function or incoherent scatter-ing factor (ISF) approach.
