What is the unit of cross sectional area?

Although the SI unit of total cross sections is m2, smaller units are usually used in practice. In nuclear and particle physics, the conventional unit is the barn b, where 1 b = 10−28 m2 = 100 fm2. Smaller prefixed units such as mb and μb are also widely used.

How big is a barn physics?

barn, unit of area used to measure the reaction cross section (generally different from the geometric cross section) of atomic nuclei and subatomic particles in the study of their interactions with other nuclei or particles. It is equal to 10−24 square cm.

What is shake in physics?

A shake is an informal metric unit of time equal to 10 nanoseconds, or 10−8 seconds. It was originally coined for use in nuclear physics, helping to conveniently express the timing of various events in a nuclear reaction, especially neutron reactions.
