// 20100114 M. Kelsey -- Remove G4CascadeMomentum, use G4LorentzVector directly
|
|
// 20100407 M. Kelsey -- Replace ::resize(0) with ::clear()
|
|
// 20100409 M. Kelsey -- Move function code to .cc files, not inlinable
|
|
// 20100418 M. Kelsey -- Add function to boost output lists to lab frame
|

|
// 20100716 M. Kelsey -- Add interface to handle G4CascadParticles
|
|
// 20100924 M. Kelsey -- Use "OutgoingNuclei" name consistently, replacing
