Description Vladimir.Ivantchenko 2021-05-25 11:35:23 CEST 
G4Scintillation::IsApplicable(...) method forbid application of the process to neutral particles, this not allows to take into account local energy deposition from neutrons and gamma. These energy depositions are small but non-zero, so should be taken into account. 

The fix is in simplification of IsApplicable(..):

return !particleType.isShortLived();

Thanks Vladimir. This is now fixed. Could you please either mark this as fixed, or assign to me so I can do it.

IsApplicable now returns false for optical photons and shortlived; true otherwise.
