unit:BARN
  a qudt:Unit ;
  dcterms:description """A barn (symbol b) is a unit of area. Originally used in nuclear physics for expressing the cross
    sectional area of nuclei and nuclear reactions, today it is used in all fields of high energy physics to express the cross
    sections of any scattering process, and is best understood as a measure of the probability of interaction between small
    particles. A barn is defined as $10^{-28} m^2 (100 fm^2)$ and is approximately the cross sectional area of a uranium nucleus.
    The barn is also the unit of area used in nuclear quadrupole resonance and nuclear magnetic resonance to quantify the
    interaction of a nucleus with an electric field gradient. While the barn is not an SI unit, it is accepted for use with the SI
    due to its continued use in particle physics.
