Detailed Description

The basf2 physics list.

Uses the Geant4 standard lists, specified by a string and adds optical processes if requested.

Constructor & Destructor Documentation

PhysicsList()

PhysicsList ( const std::string &  physicsListName )

explicit

The PhysicsList constructor.

Loads the physics list specified by its name.

Parameters

physicsListName

The name of the physics list which should be loaded.

Member Function Documentation

setProductionCutValue()

void setProductionCutValue

(

double

productionCut

)

Sets the production cut value.

If a primary particle has no longer enough energy to produce secondaries which travel at least the specified productionCut distance, two things happen: 1) Discrete energy loss ceases (no more secondaries will be produced) 2) The primary particle is tracked down to zero energy using continuous energy loss

Parameters

productionCut

The production cut value in [cm].
