Scintillation properties for xenon gas, including photon yield and time constants, are difficult to find, as traditional sources often focus on solid materials. Users are encouraged to explore simulations, such as those in Geant4, which require specific scintillation parameters for accurate modeling. A sample code snippet was shared to define scintillation properties in Geant4, highlighting the need for photon energy, refractive index, and absorption length. A suggested publication may provide additional insights, but comprehensive data remains scarce. Overall, researchers seeking this information may need to rely on simulations or specialized literature.

I am trying to find scintillation properties for xenon gas (such as the photon yield, the time constant, etc.) but so far I have come up with nothing. I searched Google, I've looked at the local library and I've searched various journals, but to no avail. Does anyone know where I would be able to find such information?

Thanks

Photon yield for a gas ? Why ? Usually light yield concerns cristals.
What is the application ?
 
I am doing a simulation in Geant4 with a xenon gas filled cylinder, and I need to take into account scintillation. Geant4 requires that the user sets the scintillation properties of the material. The simulation consists of pretty much electrons and gamma rays only.

Edit: here is a sample of code in which you define scintillation (C++ code):

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 };

myMPT1->AddProperty("RINDEX", PhotonEnergy, RefractiveIndex1,nEntries);
