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.

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/)
