Question

Is the unit of measurement for a particle beam FLUX - the femtobarn ???

Thanks

Answer 1

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

Answer 2

the inverse fermobarn is a measure sometimes of occurances per time

Answer 3

Thanks you Bob
