// G4ParticleChangeForOccurenceBiasing
|
|
//
|
|
// Class Description:
|
|
// A G4VParticleChange dedicated to occurence biasing : it
|
|
// applies weights for non-interaction over a step, and for
|
|
// interaction at the end of the step (if interaction occurs) on
|
|
// top of a given particle change, that is the one produced by a
|
|
// physics process (biased in its final state or not).
