28 // Class description:
29 //
30 // The same material can be used in regions with different cut values,
31 // and physics processes must prepare several different cross-sections
32 // for that material.
33 // The G4ProductionCutsTable has G4MaterialCutsCouple objects, each of
34 // which consists of a material paired with a cut value.
35 // G4MaterialCutsCouples objects are numbered with an index which is the
36 // same as the index of a G4PhysicsVector for the corresponding
37 // G4MaterialCutsCouple in the G4PhysicsTable.
38 // The list of G4MaterialCutsCouple objects used in the geometry setup
39 // is updated before starting the event loop in each run.
