Description

From version 9.2 of Geant4, the LowEnergy electromagnetic processes (Livermore and Penelope) have been migrated to the design introduced for the Standard EM models. In the new approach there is only one process and multiple models that can be registered to the process. We present a validation of the migrated Geant4 electromagnetic photon models for elements and compounds with respect to several libraries based on experimental data (SANDIA, EPDL97 and NIST). The cross section of all the photon models agrees with NIST within 10%.
