27 // Hadronic Process: Nuclear De-excitations
28 // by V. Lara (Oct 1998)
29 //
30 // Modified:
31 // 03.09.2008 (J.M.Quesada) for external choice of inverse cross section option
32 // 06.09.2008 (J.M.Quesada) external choices have been added for superimposed
33 // Coulomb barrier (if useSICB is set true, by default
34 // is false)
35 // 24.04.2010 (V.Ivanchenko) moved constructor and destructor to source; added
36 // two new virtual methods EmittedFragment(s) to allow
37 // more optimal work with G4Fragment objects
38 // 12.02.2013 (V.Ivanchenko) added virtual method GetLifeTime,
39 // enumerator G4EvaporationChannelType,
40 // which is defined in constructor of the class
41 //
