28 // 20100114 M. Kelsey -- Remove G4CascadeMomentum, use G4LorentzVector directly
29 // 20100405 M. Kelsey -- Pass const-ref std::vector<>
30 // 20100413 M. Kelsey -- Pass G4CollisionOutput by ref to ::collide(), use
31 // const_iterator.
32 // 20100428 M. Kelsey -- Use G4InuclParticleNames enum
33 // 20100429 M. Kelsey -- Change "case gamma:" to "case photon:"
34 // 20100517 M. Kelsey -- Follow new ctors for G4*Collider family. Make
35 // G4EvaporationInuclCollider a data member.
36 // 20100520 M. Kelsey -- Simplify collision loop, move momentum rotations to
37 // G4CollisionOutput, copy G4DynamicParticle directly from
38 // G4InuclParticle, no switch-block required. Fix scaling factors.
39 // 20100914 M. Kelsey -- Migrate to integer A and Z
40 // 20100924 M. Kelsey -- Migrate to "OutgoingNuclei" names in CollisionOutput
41 // 20110728 M. Kelsey -- Fix Coverity #28776, remove return after throw.
