Guide for Physics Lists

Scope of this Manual

This guide is a description of the physics lists class which is one of the mandatory user classes for a Geant4 application. For the most part the “reference” physic lists included in the source distribution are described here as well the modularity and electronic options. Some use cases and areas of application are also described.
