How did you specify, for example, the index of refraction, as in:
NUMENTRIES needs to be at least of size 2, and ppckov[NUMENTRIES] specifies the range of allowed photon energies. You can make that range rather small so long as it is not identical zero.

Now, this I can't explain, because G4ParticleGun::SetParticleMomentumDirection:
makes sure the direction is a unit vector.
I suspect you didn't specify a momentum range and we have a rounding problem coming from the unit vector, for the total photon momentum (vector) - used in optical photon processes - is the energy times the direction components.
