objects rather than complete pre-defined G4 physics lists. This alternative
way gives more freedom to register physics.
PhysicsConstructors are either predefined G4 PhysicsConstructors or 'local'.
They include : HadronElastic (including neutronHP), HadronInelastic,
IonsInelastic, GammaNuclear physics, RadioactiveDecay and Electromagnetic physics.
Physics constructors are either constructors provided in Geant4 (with G4 prefix)
or 'local'. They include : HadronElastic, HadronInelastic, IonsInelastic, GammaNuclear,
RadioactiveDecay and Electomagnetic.
(see geant4/source/physics_lists/constructors)
ElectromagneticPhysics is a variante of EmStandard. No step constraint is imposed for
energy loss mechanism (ionisation and brems). This is enough when spatial distribution
of deposited energy do not need to be accurate.
(see param->SetStepFunction(1., 1*mm))
HadronElasticPhysicsHP include a model for thermalized neutrons, under the control of a command
defined in NeutronHPMesseger.
GammmaNuclearPhysics is a subset of G4BertiniElectroNuclearBuilder.
ElectromagneticPhysics is a simplified version of G4EmStandardPhysics.
In perticular, no step constraint is imposed for energy loss mechanism (ionisation and brems).
This is enough when spatial distribution of deposited energy do not need
to be accurate (see param->SetStepFunction(1., 1*mm)).
Several hadronic physics options are controlled by environment variables.
To trigger them, an envHadronic.csh has been added in this example.
One must select the options wished, and do

The histos can be individually activated with the command :
