Low Energy Physics Lists

Suggested Physics lists

We suggest the following Low Energy electromagnetic physics lists, implemented in Physics constructors .

These constructors are available in the $G4INSTALL/source/physics_lists/constructors/electromagnetic directory.

They can be used in any user application, see for example $G4INSTALL/examples/extended/electromagnetic/TestEm7.

Physics constructor Content
G4EmLivermorePhysics Livermore physics models
G4EmLivermorePolarizedPhysics Livermore physics models with polarized photon models
G4LowEPPhysics Livermore physics models and Monash U. Compton model
G4EmPenelopePhysics Penelope 2008 physics models
G4EmStandardPhysics_option4 selection of most accurate physics models from Standard and Low Energy sets of models
G4EmDNAPhysics Geant4-DNA physics models
G4EmDNAPhysics_optionX Alternative Geant4-DNA physics lists (see this page)

Other Geant4 recommended Physics lists can be found on this page.

Combination with Standard Electromagnetic Physics models using Physics constructors

The uniform software design adopted since 2008 by both Geant4 electromagnetic physics working groups allows the combination of processes and models.

The above G4EmLivermorePhysics, G4EmLivermorePolarizedPhysics and G4EmPenelopePhysics Physics constructors combine Livermore (unpolarized or polarized models) or Penelope models with Standard Electromagnetic Physics models.

The combination of Geant4-DNA physics processes (adapted to the very low energy domain) with Geant4 Standard electromagnetic processes (adapted to the high energy domain) is shown in the dnaphysics and microdosimetry extended examples ($located in $G4INSTALL/examples/extended/medical/dna/)
