35 //! Class description:
36 //! This class is meant to calculate, store and provide the shell-per-shell
37 //! and the total ionisation cross section calculated by the Penelope model.
38 //! The information is provided to other physics models, notably: Penelope
39 //! ionisation model and Penelope "PIXE" model. Cross sections are calculated
40 //! per material-cut couple and stored as G4PenelopeCrossSection objects.
