Physics Reference Manual URL – http://geant4.web.cern.ch/geant4/UserDocumentation/UsersGuides/ PhysicsReferenceManual/fo/PhysicsReferenceManual.pdf http://geant4.web.cern.ch/geant4/UserDocumentation/UsersGuides/ PhysicsReferenceManual/fo/PhysicsReferenceManual.pdf – No more html version, only pdf version is available. The purpose of this manual – to present the theoretical formulation, model, or parameterization of the physics interactions included in Geant4 – to describe the probability of the occurrence of an interaction and the sampling mechanisms required to simulate it, and – to serve as a reference for toolkit users and developers who wish to consult the underlying physics of an interaction. The Physics Reference Manual contains gaps in documentation which correspond to un-implemented interactions. There are also a few sections in which documentation is slight.
