|
|
// Class Description:
|
|
// A G4VBiasingOperator concrete implementation example to
|
|
// illustrate how to bias physics processes cross-section for
|
|
// one particle type.
|
|
// The G4VBiasingOperation G4BOptnChangeCrossSection is
|
|
// selected by this operator, and is sent to each process
|
|
// calling the operator.
|
|
// A simple constant bias to the cross-section is applied,
|
|
// but more sophisticated changes can be applied.
