Inorganic Scintillator

I want to obtain the energy spectra of the Cs-137 crystal that I am designing a CsI(Tl) scintillator. I am shooting a 662 keV gamma in the crystal. I can see the scintillation photons being produced.

But I want to find the number of scintillation photons hitting the PMT is there any example /code for this?

Thank You
