30 // Collects generated cascade data (using Collider::collide() interface)
31 // and computes the nuclear recoil kinematics needed to balance the event.
32 //
33 // 20100909 M. Kelsey -- Inspired by G4CascadeCheckBalance
34 // 20100909 M. Kelsey -- Move G4IntraNucleiCascader::goodCase() here, add
35 // tolerance for "almost zero" excitation energy, add function
36 // to manually override excitation energy
37 // 20100910 M. Kelsey -- Drop getRecoilFragment() in favor of user calling
38 // makeRecoilFragment() with returned non-const pointer. Drop
39 // handling of excitons.
40 // 20100914 M. Kelsey -- Migrate to integer A and Z
41 // 20100921 M. Kelsey -- Return G4InuclNuclei using "makeRecoilNuclei()".
42 // Repurpose "makeRecoilFragment()" to return G4Fragment.
43 // 20100924 M. Kelsey -- Add raw excitation energy (mass difference) function
44 // 20110214 M. Kelsey -- Replace "model" with G4InuclParticle::Model enum
45 // 20110722 M. Kelsey -- For IntraNucleiCascader, take G4CollOut as argument
46 // 20130620 Address Coverity complaint about missing copy actions
