The Geant4 Binary Cascade is an intranuclear cascade propagating primary and
secondary particles in a nucleus. Interactions are
between a primary or secondary particle and an individual nucleon of the
nucleus, leading to the name Binary Cascade. Cross section data are used to
select collisions. Where available, experimental cross sections are used
by the simulation. Propagating of particles is the nuclear field is done by
numerically solving the equation of motion. The cascade terminates
when the average and maximum energy of secondaries is below threshold. The
remaining fragment is treated by precompound and de-excitation models documented
in the corresponding chapters.
