What is the barn?

The barn is a unit of area and is used in particle physics with the symbol b.

It represents approximately the area of the cross-section of a uraneum nucleus, so is very small compared to most other recognised units of area.

It is also used to measure the interaction of a nucleus with an electric field gradient in nuclear quadrupole and magnetic resonance.
