Livermore photoelectric model bug notification for Geant4 9.6

We are sorry to inform Geant4 users that a bug as been identified in the simulation of photoelectric effect using the G4LivermorePhotoelectricModel class, which was released in the Geant4 9.6 release.

In order to solve this issue, users can :

• either download the corrected class (G4LivermorePhotoElectricModel.cc) from http://bugzilla-geant4.kek.jp/attachment.cgi?id=194 into their $G4INSTALL/source/processes/electromagnetic/lowenergy/src directory and recompile their installation of Geant4

• or, if the user is using the G4EmLivermorePhysics constructor in his/her application, he/she may copy directly the G4EmLivermorePhysics.hh and G4EmLivermorePhysics.cc files into his/her ./include and ./src application directories, then copy the G4LivermorePhotoElectricModel.hh and the corrected G4PhotoElectricModel.cc 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 G4EmLivermorePhysics.cc 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 G4LivermorePhotoElectricModel.cc is available from http://bugzilla-geant4.kek.jp/attachment.cgi?id=194

The bug will be corrected in the next patch to Geant4 9.6.
