My geometry is a collimated phoswitch detector. The collimator is made up of materials Ta(z=73) and Pb(z=82). Material Ta is defined by codes: density = 16.66*g/cm3; a = 180.95*g/mole; G4Material* Ta = new G4Material(name="Tan" , z=73., a, density); The PhysicsList.cc includes these codes to activate the auger electron emission: if (particleName == "gamma") { pmanager->AddDiscreteProcess(new G4LowEnergyCompton); LePeprocess = new G4LowEnergyPhotoElectric(); LePeprocess->ActivateAuger(true); pmanager->AddDiscreteProcess(LePeprocess); pmanager->AddDiscreteProcess(new G4LowEnergyGammaConversion); } Everything seems right when I start my program. The auger electron data is loaded when below message appears: G4AugerData for Element no. 8 are loaded G4AugerData for Element no. 11 are loaded G4AugerData for Element no. 13 are loaded G4AugerData for Element no. 14 are loaded G4AugerData for Element no. 29 are loaded G4AugerData for Element no. 53 are loaded G4AugerData for Element no. 55 are loaded G4AugerData for Element no. 73 are loaded G4AugerData for Element no. 82 are loaded AugerTransitionTable complete But when I use "/run/beamOn 1" to begin a gamma-ray simulation, the program halts and shows a message as soon as transportation in the material Ta: G4AtomicDeexcitation: No Auger transition found *** G4Exception: Aborting execution *** If I construct my collimator only with Pb, or comment the codes "LePeprocess->ActivateAuger(true)", the program will always run till the end of RunAction without any error.
