0028 // Class Description
0029 // Model implementation for pre-equilibrium decay models in geant4.
0030 // To be used in your physics list, in case you neeed this kind of physics.
0031 // Can be used as a stand-allone model, but also in conjunction with
0032 // an intra-nuclear transport, or any of the string-parton models.
0033 // Class Description - End
0034 //
0035 // Modified:
0036 // 03.09.2008 J.M.Quesada added external choice of inverse
0037 //            cross section option.(default OPTxs=3)
0038 // 06.09.2008 J.M.Quesada external choices have been added for:
0039 //     - superimposed Coulomb barrier (if useSICB=true, default false)
0040 //     - "never go back"  hipothesis (if useNGB=true, default false)
0041 //     - soft cutoff from preeq. to equlibrium (if useSCO=true, default false)
0042 //                - CEM transition probabilities (if useCEMtr=true)
0043 // 30.10.2009 J.M.Quesada CEM transition probabilities are set as default
0044 // 20.08.2010 V.Ivanchenko Cleanup of the code
0045 // 03.01.2012 V.Ivanchenko Added pointer to G4ExcitationHandler to the
0046 //                         constructor
