In order to solve this issue, users can :

  • or, if the user is using the G4EmLivermorePhysics constructor in his/her application, he/she may copy directly the G4EmLivermorePhysics.hh and files into his/her ./include and ./src application directories, then copy the G4LivermorePhotoElectricModel.hh and the corrected files in the same directories, and recompile his/her application. Location of files:
    • the file G4EmLivermorePhysics.hh is located in the Geant4 source directory $G4INSTALL/source/physics_lists/builders/include
    • the file is located in the Geant4 source directory $G4INSTALL/source/physics_lists/builders/src
    • the file G4LivermorePhotoElectricModel.hh is located in the Geant4 source directory $G4INSTALL/source/processes/electromagnetic/lowenergy/include
    • the corrected file is available from
