Physics Reference Manual URL – PhysicsReferenceManual/fo/PhysicsReferenceManual.pdf 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.
