Where can I find scintillation properties for xenon gas?

[ultimateguy]

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

Hi,

Xe @ PDG[/color]
Xe @ webelements[/color]

I am not sure that helps however. If I needed to get your informations, I guess I would run a simulation.

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 };

Ok, unfortunately, I cannot help you. Maybe this publication :
