Picobarns to barns
Type a value in pb to get it in b instantly.
1×10⁻¹²b
That's 100,000,000× as big as a neutrino interaction, while ordinary neutron scattering is 4,000,000,000,000× bigger. A disc that size would have a radius of about 5.642×10⁻⁶ fm.
What it means
How big a target is that?
A cross section is an effective area, not a physical one. A strongly absorbing nucleus can present a target far larger than itself.
The math
How to convert pb to b
To convert picobarns to barns, multiply by 1×10⁻¹².
Example: 1 pb × 1×10⁻¹² = 1×10⁻¹² b.
In the other direction, 1 b = 1×10¹² pb.
