Question XRF with secondary electrons  

Keywords: XRF physics list
Forum: Physics List
Date: 28 Aug, 2007
From: John May <john.may@go4more.de>

Hello,

I'm trying to simulate a simple XRF setup. At the moment I have two 
problems: 
 
the fluorescence energies are not like expected but always a little 
below the literature values. 

And it seems that activating   

G4LowEnergyIonisation * LeIoprocess = new G4LowEnergyIonisation("IONI");

LeIoprocess->ActivateAuger(true);

LeIoprocess->ActivateFluorescence(true); 

have no influence at all.

Anyone can help me with a correct physics list which gives the right 
fluorescence energies and includes the fluorescence from the 
secondary electrons? Or someone can gives a hint? 

Thanks a lot

John
