Nuclear interaction length — is the mean path length required to reduce the numbers of relativistic charged particles by the factor 1/e, or 0.368, as they pass through matter. Comprehensive tables for radiation lengths and other properties of materials are available from the … Wikipedia
Radiation length — In physics, the radiation length is a characteristic of a material, related to the energy loss of high energy, electromagnetic interacting particles with it.DefinitionHigh energy electrons predominantly lose energy in matterby bremsstrahlung, and … Wikipedia
