Below is the calculations done to determine the probability of pair production depending on thickness of the scintillator.

Molecules per

(NOTE: is just the density of the scintillator material and N[A] is Avagodro's number)Molecules per

Weighted cross-section

Probability of interaction (%)

All cross sections listed here are pair production cross-sections

For carbon

orFor carbon

orFor hydrogen

orFor hydrogen

orAvagodro's number

Density of polyvinyl toluene (a common scintillator material)

For the sample calculation the thickness will be set to 1 cm just to get probability per cm

So entering all the numbers into the 4 initial equations gives the following answers:

Molecules per
