Question How to explain energy spectra of emmited photons from a scintillator, in my code?

Hi, Consider this code from ExN06DetectorConstruction.cc:

  const G4int nEntries = 32;

  G4double PhotonEnergy[nEntries] =
            { 2.034*eV, 2.068*eV, 2.103*eV, 2.139*eV,
              2.177*eV, 2.216*eV, 2.256*eV, 2.298*eV,
              2.341*eV, 2.386*eV, 2.433*eV, 2.481*eV,
              2.532*eV, 2.585*eV, 2.640*eV, 2.697*eV,
              2.757*eV, 2.820*eV, 2.885*eV, 2.954*eV,
              3.026*eV, 3.102*eV, 3.181*eV, 3.265*eV,
              3.353*eV, 3.446*eV, 3.545*eV, 3.649*eV,
              3.760*eV, 3.877*eV, 4.002*eV, 4.136*eV };

1. How translate Geant4 these values in such array? Only one by one, or not? I mean, for example, if energy of a photon be 2.035*eV (very close to 2.034*eV), do Geant4 accept it as a value of the array? From C++, I know the answer in NO.

2. Perhaps because matter of origin of these photons is a scintillator, so only "some energies" will release; Is that correct?

3. Please observe attached pic, about NE102A scintillator The emission spectra is "continuous". How to explain wavelengths of emitted photons, in my code as an array?

Regards
