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