Incoherent inelastic scattering. The most interesting component of thermal scattering is called "incoherent inelastic" because the neutron exchanges energy with the target molecule or crystalline lattice and all the scattered waves are assumed to combine incoherently without interference effects. This component is described in terms of a scattering function called "S of alpha and beta, where alpha and beta are reduced values for momentum transfer and energy transfer, respectively...  1, record 1, English, - incoherent%20inelastic%20scattering

The spectrum of X-rays emitted when a substance is bombarded with energetic particles or radiation. It consists of a "characteristic spectrum", resulting from specific electronic transitions within the atoms of the substance, superimposed on a "continuous spectrum" resulting from inelastic collisions of particles or incoherent scattering of the exciting radiation.  2, record 2, English, - X%2Dray%20spectrum

La "diffraction des rayons X" est (...) devenue un moyen fondamental pour identifier les minéraux (...) Dans le dispositif le plus courant, le minéral est broyé et disposé sur une lame de verre ou dans la petite cuvette d'un porte-échantillon. Le spectre de diffraction des rayons X est enregistré d'une part graphiquement et de l'autre, dans les appareils modernes, par comptage d'impulsions (...)  2, record 2, French, - spectre%20de%20diffraction%20des%20rayons%20X
