In G4ParticleWithCuts::SetCuts() method,

1. CalcEnergyCuts()

• As for each material
  • build a range table as a function of kinetic energy
  • convert the given range to kinetic energy
    
  2. BuildPhyicsTable()
• As for each process in the process manager
  make its physics table by G4VProcess::BuildPhysicsTable()
  
  • PhysicsTable is a collection of cross sections (G4PhysicsVector) for all materials
