Question Sodium Iodide Scintillation 

Forum: Processes Involving Optical Photons

I wish to model sodium iodide for scintillation purpose using gamma radiation.

How do I get photon energy of interest for this purpose?

Thank you!

For reference code:
Like for photon energy and their fast components:
G4double Scnt_PP[NUMENTRIES] = { 6.6*eV, 6.7*eV, 6.8*eV, 6.9*eV,
                                       7.0*eV, 7.1*eV, 7.2*eV, 7.3*eV, 7.4*eV };

G4double Scnt_FAST[NUMENTRIES] = { 0.000134, 0.004432, 0.053991, 0.241971,
                                         0.398942, 0.000134, 0.004432, 0.053991,
                                         0.241971 };

For other properties, I am more confident:

G4double rind[NUMENTRIES]={1.77475, 1.77475, 1.77475, 1.77475, 1.77475,
        1.77475, 1.77475, 1.77475, 1.77475};

G4double abs[NUMENTRIES]={2.56*cm, 2.56*cm, 2.56*cm, 2.56*cm, 2.56*cm,
        2.56*cm, 2.56*cm, 2.56*cm, 2.56*cm};

Scnt_MPT->AddConstProperty("SCINTILLATIONYIELD", 43000./MeV); Scnt_MPT->AddConstProperty("RESOLUTIONSCALE", 2.0); Scnt_MPT->AddConstProperty("FASTTIMECONSTANT", 230.*ns);
