// Class descriptions:
|
||||
// G4IonParametrisedLossTable: Wrapper class for classes of the material
|
||||
// category, which maintain stopping power vectors for ions. This wrapper
|
||||
// class includes a cache for faster access of stopping powers and builds
|
||||
// stopping power vectors for compounds using Bragg's additivity rule.
|
||||
// G4IonLossTableHandle: A handle class for G4IonParametrisedLossTable
|
||||
// G4DummyScalingAlgorithm: A dummy algorithm to scale energies and
|
||||
// stopping powers (may be replaced with an algorithm, which relies on
|
||||
// dynamic information of the particle: This may be required if stopping
|
||||
// power data is scaled using an effective charge approximation).
