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 |
