// A G4VBiasingOperator concrete implementation example to

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

|
// In the present case, the GB01BOptrChangeCrossSection
|
|
// operator, that is made to bias processes of one particle
|
|
// type is instancied several times, one for each particle type
|
|
// to bias.
