// G4BOptrForceCollision
|
|
//
|
|
// Class Description:
|
|
//
|
|
// A G4VBiasingOperator that implements a "force collision" a la
|
|
// MCNP. This is meant for neutral particles.
|
|
// When the track enters the volume, it is cloned. One copy makes
|
|
// a forced free flight up to the volume exit. The other copy makes
|
|
// a forced collision inside the volume.
|
