Note optical photons question

Hello,

I use the optical photons processes and I ran into something that, I think, could be improve. Actually, in a dielectric_metal surface, incorrect behavior happens if one gives the reflectivity or the efficiency of a surface through AddConstProperty instead of AddProperty. Maybe I missed something in the documentation, but it seems natural to use AddConstProperty if one wants the property to be independant of wavelength. As an example, change the line

photocath_mt->AddProperty("REFLECTIVITY",Ephoton,photocath_REFL,num);

by

photocath_mt->AddConstProperty("REFLECTIVITY",0.0);

in the extended/optical/LXe/src/LXeMainVolume.cc and see the results.

Otherwise, it seems like a considerable effort was made by François-Xavier Gentit to model optical photons http://gentit.home.cern.ch/gentit/litrani/

I wonder if GEANT4 could benefit from some parts of this work.

Philippe
