Is the unit of measurement for a particle beam FLUX - the femtobarn ???
No. The Barn is a unit of area of the beam.
When you say partical beam flux, it could mean mass flux, collision occurance flux. You have to be specific.
Normally flux is (things/(area))/time
the inverse fermobarn is a measure sometimes of occurances per time
Thanks you Bob
