In nuclear physics, an inelastic collision is one in which the incoming particle causes the nucleus it strikes to become excited or to break up. Deep inelastic scattering is a method of probing the structure of subatomic particles in much the same way as Rutherford probed the inside of the atom (see Rutherford scattering).
In chemistry, nuclear physics, and particle physics, inelastic scattering is a process in which the internal states of a particle or a system of particles change after a collision. Often, this means the kinetic energy of the incident particle is not conserved (in contrast to elastic scattering ).
In physics, the coefficient of restitution (COR, also denoted by e), can be thought of as a measure of the elasticity of a collision between two bodies. It is a dimensionless parameter defined as the ratio of the relative velocity of separation after a two-body collision to the relative velocity of approach before collision.
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 ...
Inelastic collision. If most or all of the total kinetic energy is lost (dissipated as heat, sound, etc. or absorbed by the objects themselves), the collision is said to be inelastic; such collisions involve objects coming to a full stop. An example of this is a baseball bat hitting a baseball - the kinetic energy of the bat is transferred to ...
In physics, an elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same. In an ideal, perfectly elastic collision, there is no net loss of kinetic energy into other forms such as heat, noise, or potential energy.
In nuclear physics, area cross-sections (e.g. σ in barns or units of 10 −24 cm 2), density mean free path (e.g. τ in grams/cm 2), and its reciprocal the mass attenuation coefficient (e.g. in cm 2 /gram) or area per nucleon are all popular, while in electron microscopy the inelastic mean free path [14] (e.g. λ in nanometers) is often ...
Such a collision is inelastic, since some of the kinetic energy is transformed to potential energy by exciting some of the internal degrees of freedom of the nucleus to form an excited state. As the energy of the neutron is lowered, the collisions become predominantly elastic , i.e., the total kinetic energy and momentum of the system (that of ...
