// A G4VBiasingOperator concrete implementation example to

// illustrate how an operator can make use of another operator.

// In the present case, the G4ChannelingOptrChangeCrossSection
|
|
// operator, that is made to bias processes of one particle
|
|
// type is instancied several times, one for each particle type
|
|
// to bias.
