Inelastic Scattering

 

a collision of particles that is accompanied by a change in the internal state of the particles, conversion into other particles, or the additional production of new particles. Examples of inelastic scattering are the excitation or ionization of atoms during collision, nuclear reactions, the transformations of elementary particles by collision, and the multiple production of particles. Each type (channel) of inelastic scattering has its own minimum (threshold) collision energy, below which a given process is impossible. The total scattering probability when particles collide, which is characterized by a total effective scattering cross section, is the sum of the probabilities of elastic scattering and inelastic scattering; in this case, there exists a relation, given by the so-called optical theorem, between elastic and inelastic processes.

Inelastic scattering occurs through much larger angles on average and tends to miss the detector, so the method of fixed forced detection (FFD) has been introduced to improve the efficiency of the simulation [23].
Any narrow-line light source sees spontaneous Brillouin as weak inelastic scattering from thermal acoustic waves.
The more intense result of [sup.197]Au is attributed not only to its density (higher than [sup.139]La) but also to the combined effect of inelastic scattering (threshold at 0.1MeV).
While fluorescence results from the excitation of emitters by an incident field and the subsequent emission from an excited state to the ground state, which is determined by the competition between the radiative and non-radiative decay processes, Raman scattering is a purely inelastic scattering process between photons and molecules, mediated by vibrational or rotational modes of the molecules.

The opening paper describes typical experimental equipment and methods for measuring inclusive deep inelastic and semi-inclusive deep inelastic scattering of polarized leptons off polarized targets.
Inelastic light scattering from a crystal can be as an inelastic scattering of a photon from acoustic phonons.
The inelastic scattering of light from any sample is called the Raman effect, named for the Nobel prize-winner C.V.
(74) Inelastic scattering of an electron in amorphous ice indicates that electron energy losses greater than 1 eV rarely occurs for kinetic energies smaller than the HOMO--LUMO gap (~7eV) of bulk water.
During inelastic scattering on electrons, the incident particle can transfer energy to the atom, raising it to a higher energy level (excitation), or it may transfer enough energy to remove an electron from the atom (ionization).
In the less common but more important inelastic scattering, the incident light and the emitted light are of different colors, because the electrons expend kinetic energy through vibration.
