Description Jingke 2012-11-13 23:20:56 CET 
Auger electron and X-rays used to be produced after inverse beta decay of 40K in G4.9.0, but they don't seem to be there in G4.9.5. I am using the DMXPhysicsList.cc in the underground physics advanced example. Thank you!

Auger electron and X-rays are covered by electromagnetic processes.
Comment 2 Vladimir.Ivantchenko 2012-11-17 12:39:34 CET 
DMX advanced example PhysicsList was not modified for along time. Due to this new features introduced in recent releases of Geant4 are not available. To have Auger electron production after radioactive decay can be activate as it is shown in examples/extended/radioactive_decay.

Adding the following three lines:

  // switch on fluorescence, PIXE and Auger:
  opt.SetFluo(true);
  opt.SetPIXE(true);
  opt.SetAuger(true);


To the DMXPhysicsList.cc at the end of ConstructEM() method should fix the problem.

Auger electron and X-rays were switched off by default since Geant4 version 9.3 (I think).

As an Auger macro is not included in the example is difficult to verify if the functionality has now returned in a user's own application, albeit with a physics list from the advanced example.
