Dear all,
As we know, the reaction rate can be calculated as following:
R = N * σ * Φ (1)
Where R is reaction rate (events/s/cm3)
σ is cross section (cm2)
Φ is flux of incident particle beam (particles/s/cm2
N is density of target (atoms/cm3)
Logically, there is a limitation of R, because R cannot larger than the number of incident particles. But as equation (1), if Φ is constant, that means the number of incident particles is unchanged, and N increases, R will increase without any limitation. So if N is big enough, R will pass the limit that I talked above.
I hope that you can understand my idea well, because, my English is so bad.
Thank you very much,
