How to switch of Doppler broadening in Compton scattering?

I want to use a physics list which will enable me to switch off Doppler broadening in Compton scattering for my simulation which is related to medical imaging application where gamma energy range is 10 keV to 2 MeV. I had gone through “Electromagnetic physics constructors” chapter of “Geant4 Guide For Physics Lists Release 10.5” manual, and I could not find anything related to Doppler effect.

Is there any way of switching of Doppler broadening in Geant4 simulation?


you need to use G4EmStandardPhysics_option4 or EMZ extension of reference Physics Lists.
