Shed (physics)
From Wikipedia, the free encyclopedia
A shed is a non-SI unit of area or cross-section used in nuclear physics. One shed is defined as being equal to 10−24 barn, an extraordinarily small unit of area. As the unit is so small, it has only had minimal use. It was used when studying the neutrino, and other such sub-atomic particles. The term never gained wide acceptance though. The name was derived by analogy with the barn.[1] It is the smallest unit of measurement used in sub-atomic physics.[2]
A shed is to a barn as a barn is to a square centimeter (a barn is 10-24 square centimeters).
1 shed = 10−24 barn (b) = 10−48 square centimeters (cm²) = 10−22 square femtometers (fm²) = 10−52 square meters (m²)
