31// History:
32// -----------
33// 26 Nov 2008   L. Pandola   1st implementation. Migration from EM process
34//                            to EM model. Physics is unchanged.
35// 21 Oct 2009   L. Pandola   Remove un-necessary methods and variables to handle
36//                            AtomicDeexcitationFlag - now demanded to G4VEmModel
37//                            Add ActivateAuger() method
38// 29 Mar 2010   L. Pandola   Added a dummy ComputeCrossSectioPerAtom() method issueing a
39//                            warning if users try to access atomic cross sections via
40//                            G4EmCalculator
41// 15 Apr 2010   L. Pandola   Implemented model's own version of MinEnergyCut()
