Static defects scatter elastically the charge carriers. Electrons do not loose memory of the phase contained in their wave function and thus propagate through the sample in a coherent way. By contrast, electron-phonon or electron-electron collisions are inelastic and generally destroy the phase coherence. The resulting inelastic mean free path, Li , which is the distance that an electron travels between two inelastic collisions, is generally equal to the phase coherence length, the distance that an electron travels before its initial phase is destroyed ...

Since the wavelength is of the order of lattice distances, electrons that are scattered elastically undergo constructive and destructive interference (as with X-rays in XRD). The back-scattered electrons form a pattern of spots on a fluorescent screen from which the symmetry and structure of the surface may be deduced. 

Neutrons may collide with nuclei causing one of the following reactions inelastic scattering, elastic scattering, radiative capture, or fission. 

Fast neutrons rapidly degrade in energy by elastic collisions when they interact with low atomic number materials. As neutrons reach thermal energy, or near thermal energies, the likelihood of capture increases. In present day reactor facilities the thermalized neutron continues to scatter elastically with the moderator until it is absorbed by fuel or non-fuel material, or until it leaks from the core. 

One way to think about the Landauer formula is to say conductance is scattering [69]. In fact, conductance is elastic scattering, because in the original Landauer approach, all scattering is considered to be elastic - particles leave the electrode and are scattered elastically until they make it into the other electrode (or not). Inelastic events are not included, at least conceptually.

Figure 6.7 The principle of LEED is that a beam of monoenergetic electrons scatters elastically from a surface. Because of the periodic order of the surface atoms, electrons show constructive interference in directions for which the path lengths of the electrons differ by an integral number times the electron wavelength. Directions of constructive interference are made visible by collecting the scattered...

Figure 9.27 In Raman spectroscopy, light from a laser is shone at a sample. It is monochromated at a frequency of v0. Most of the light is transmitted. Most of the scattered light is scattered elastically, so its frequency remains at v0 this is Rayleigh scattered light. Raman scattered light has a frequency V(SCattered) = v0 — vibration) The sample is generally in solution...

Laser Raman spectroscopy uses a light scattering process where a specimen is irradiated monochromatically with a laser. The visible light that has passed into the specimen causes the photons of the same wavelength to be scattered elastically, while... 

An electron beam with energy 150 eV has a wavelength of 1 A, which is suitable to probe crystallographic structures. The typical electron energy used in LEED is 20-500 eV. The mean free path of such electrons in metals is 5-10 A. The electrons scatter elastically from the surface. LEED has been discussed in many textbooks (Ashcroft and Mermin, 1985 Zangwill, 1988). 

The interpretation given above is simplified, since fluorescence is not the only process that allows the atom to lose its excess energy. Other phenomena such as Rayleigh scattering (elastic scattering) and the Compton effect (inelastic scattering with release of Compton electrons) can complicate the X-ray emission spectrum.

The electrons that are not scattered elastically lose their energy on penetrating a phosphor crystal by inelastic scattering and formation of secondary electrons. 

Consider a particle with mass mi scattering elastically from a particle (at rest) with mass m2. If mj > m2, show that the scattering angle cannot exceed sin 1(m2/mi). 

In classical terms ( mixing can be thought of in a simple way. When an Ar atom, for example, enters the Rydberg electron s orbit the electron can scatter elastically from the Ar. The reorientation of the orbit corresponds to a new (. If we pursue this notion a little further we can understand qualitatively the dependence... 

We continue with the full description in three-dimensional space and consider first, as an introduction to reactive scattering, elastic two-body scattering, and then generalize to reactive (three-body) scattering [14].
