|
|
|
|
// A prototype of the Gheisha High Energy collision model.
|
|
// It includes all Physics Routines from Geant3,
|
|
// relevant for simulation of hadronic processes
|
|
// above approx. 20 GeV incident momentum.
|
|
// Not included are the Physics Routines for
|
|
// stopping particles, the low energy neutron
|
|
// slowing down description and the low energy
|
|
// nuclear reactions a(A,A')b.
|
|
// All routines pass the compiler and give
|
|
// some reasonable numbers as output.
|
|
// A statistically significant comparison
|
|
// with GEANT3 and experimental data has
|
|
// still to be done.

// derives from the G4HEInelastic class. This class contains the various

// algorithms needed to implement the interaction. These include
|
|
// lambda-fragmentation, meson and nucleon cluster formation and decay,

// nuclear cascade, and nuclear de-excitation.
