Barn (b) - nuclear/particle cross-section area
Barn is a non-SI unit of area used in nuclear and particle physics to express interaction cross-sections. The name originated humorously during the Manhattan Project (“as big as a barn”).
- Symbol: b
- System: Non-SI (accepted in high-energy/nuclear physics)
- Exact relations: 1 b = 10⁻²⁸ m² = 10⁻²⁴ cm² = 100 fm²
- Common submultiples: 1 mb = 10⁻³ b; 1 µb = 10⁻⁶ b; 1 nb = 10⁻⁹ b; 1 pb = 10⁻¹² b; 1 fb = 10⁻¹⁵ b; 1 ab = 10⁻¹⁸ b
- Related usage: integrated luminosity often quoted in inverse barns (e.g., fb⁻¹)
- Typical examples: neutron capture and scattering cross-sections; collider process cross-sections reported from barns down to picobarns and femtobarns
