Re: Optical photons

Hello Joe
a late answer..
no, there is no competition. I just checked, enabling both cere and scint
gives the sum of the optical photons generated in the two processes.
However, the yield of cherenkov photons can b very small with respect to
scintillation ones, to the point of being undetectable.
