| Details | A gigabarn (Gb) is a unit of area used primarily in nuclear and particle physics to measure cross-sectional areas of particle interactions. A cross-sectional area is a measure of the probability that a given interaction will occur, such as the collision or scattering of particles. The name "barn" comes from the colloquial expression "big as a barn" because it was initially used to represent relatively large cross-sectional areas in nuclear reactions. 1 gigabarn is equal to 10^9 barns, where 1 barn is equal to 10^-28 square meters (m²). Therefore, 1 Gb is equal to 10^-19 square meters (m²). In scientific notation: 1 Gb = 1 x 10^9 barn 1 barn = 1 x 10^-28 m² 1 Gb = 1 x 10^-19 m² The gigabarn (Gb) is a large unit compared to a barn; it is used to represent larger cross-sectional areas or to compare cross sections of various particle interactions in high-energy physics experiments. |
