Nuclear Interaction Length

	Nuclear Interaction Length Nuclear interaction length is the mean distance travelled by a hadronic particle before undergoing an inelastic nuclear interaction.

	Nuclear Collision Length Nuclear collision length is the mean free path of a particle before undergoing elastic scattering or a nuclear reaction, for a given particle in a given medium. The collision length is smaller than the nuclear interaction length because the latter excludes the elastic and quasi-elastic (diffractive) reactions from its definition.

	Radiation Length In particle physics, the radiation length is a characteristic of a material, related to the energy loss of high energy elementary particle, particles electromagnetically interacting with it. It is defined as the mean length (in cm) into the material at which the energy of an electron is reduced by the factor 1/E (mathematical constant), ''e''. Definition In materials of high atomic number (e.g. tungsten, uranium, plutonium) the electrons of energies >~10 MeV predominantly lose energy by , and high-energy photons by pair production. The characteristic amount of matter traversed for these related interactions is called the radiation length , usually measured in g·cm−2. It is both the mean distance over which a high-energy electron loses all but of its energy by , and of the mean free path for pair production by a high-energy photon. It is also the appropriate length scale for describing high-energy particle shower, electromagnetic cascades. The radiation length for a given ...
