28 // Takes an arbitrary excited or unphysical nuclear state and produces
29 // a final state with evaporated particles and (possibly) a stable nucleus.
30 //
31 // 20100922 M. Kelsey -- Remove convertFragment() function, pass buffer
32 // instead of copying, clean up code somewhat
33 // 20100925 M. Kelsey -- Use new G4InuclNuclei->G4Fragment conversion, and
34 // G4ReactionProducts -> G4CollisionOutput convertor. Move Z==0
35 // explosion condition to base-class function.
36 // 20100926 M. Kelsey -- Move to new G4VCascadeDeexcitation base class,
37 // replace getDeexcitationFragments() with deExcite().
38 // 20110214 M. Kelsey -- Follow G4InuclParticle::Model enumerator migration
39 // 20110803 M. Kelsey -- Add post-deexcitation diagnostic messages
40 // 20120120 V. Ivanchenko -- Pre-compound model and its handler should not be deleted here
41 // 20130621 Replace collide() interface with deExcite() using G4Fragment ref
42 // 20130622 Inherit from G4CascadeDeexciteBase, add verbosity interface
43 // to pass to PreCompound
44 // 20140508 Per V. Ivanchenko, attempt to use common instance of PreCompound.
