  2. Price elasticity of demand - Wikipedia

    en.wikipedia.org/wiki/Price_elasticity_of_demand

    Breadth of definition: The broader the definition of a good (or service), the lower the elasticity, because it is no longer possible to . For example, McDonalds hamburgers will probably have a relatively high elasticity of demand (as customers can switch to other fast-food options), whereas food in general will have an extremely low elasticity ...

  3. Elasticity (economics) - Wikipedia

    en.wikipedia.org/wiki/Elasticity_(economics)

    If supply elasticity is zero, the supply of a good supplied is "totally inelastic", and the quantity supplied is fixed. It is calculated by dividing the percentage change in quantity supplied by the percentage change in price. [15] The supply is said to be inelastic when the change in the prices leads to small changes in the quantity of supply.

  4. Deep inelastic scattering - Wikipedia

    en.wikipedia.org/wiki/Deep_inelastic_scattering

    Feynman diagram representing deep inelastic scattering of a lepton (l) on a hadron (h), at leading order in perturbative expansion. The virtual photon (γ * ) knocks a quark (q) out of the hadron. In particle physics , deep inelastic scattering is the name given to a process used to probe the insides of hadrons (particularly the baryons , such ...

  5. Inelastic scattering - Wikipedia

    en.wikipedia.org/wiki/Inelastic_scattering

    Inelastic scattering is common in molecular collisions. Any collision which leads to a chemical reaction will be inelastic, but the term inelastic scattering is reserved for those collisions which do not result in reactions. [3] There is a transfer of energy between the translational mode (kinetic energy) and rotational and vibrational modes.

  6. Electron energy loss spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Electron_energy_loss...

    Here mfp is the mean free path of electron inelastic scattering, which has been tabulated for most elemental solids and oxides. [ 14 ] The spatial resolution of this procedure is limited by the plasmon localization and is about 1 nm, [ 6 ] meaning that spatial thickness maps can be measured in scanning transmission electron microscopy with ~1 ...

  7. Inelastic mean free path - Wikipedia

    en.wikipedia.org/wiki/Inelastic_mean_free_path

    Universal curve for the electron inelastic mean free path in elements based on equation (5) in. [1] If a monochromatic , primary beam of electrons is incident on a solid surface, the majority of incident electrons lose their energy because they interact strongly with matter , leading to plasmon excitation, electron-hole pair formation, and ...

  8. Pseudorapidity - Wikipedia

    en.wikipedia.org/wiki/Pseudorapidity

    In hadron collider physics, the rapidity (or pseudorapidity) is preferred over the polar angle because, loosely speaking, particle production is constant as a function of rapidity, and because differences in rapidity are Lorentz invariant under boosts along the longitudinal axis: they transform additively, similar to velocities in Galilean ...
