// Hadronic Process: Nuclear De-excitations
|
|
// by V. Lara (May 1998)
|
|
//
|
|
// Modifications:
|
|
// 30 June 1998 by V. Lara:
|
|
// -Using G4ParticleTable and therefore G4IonTable
|
|
// it can return all kind of fragments produced in
|
|
// deexcitation
|
|
// -It uses default algorithms for:
|
|
// Evaporation: G4StatEvaporation
|
|
// MultiFragmentation: G4DummyMF (a dummy one)
|
|
// Fermi Breakup model: G4StatFermiBreakUp
|
|
//
|
|
// 03 September 2008 by J. M. Quesada for external choice of inverse
|
|
// cross section option
|
|
// 06 September 2008 JMQ Also external choices have been added for
|
|
// superimposed Coulomb barrier (if useSICBis set true, by default is false)
|
|
// 23 January 2012 by V.Ivanchenko remove obsolete data members; added access
|
|
// methods to deexcitation components
|
|
//
