28 // Class Description:
29 //
30 // A G4VBiasingOperator that implements a "force collision" a la
31 // MCNP. This is meant for neutral particles.
32 // When the track enters the volume, it is cloned. One copy makes
33 // a forced free flight up to the volume exit. The other copy makes
34 // a forced collision inside the volume.
35 //
