30 // History:
31 // -----------
32 // 12 Jan 2009 L. Pandola 1st implementation. Migration from EM process
33 // to EM model. Physics is unchanged.
34 // 23 Oct 2009 L. Pandola remove un-necessary methods to manage atomic
35 // deexcitation (done by G4VEmModel)
36 // 01 Jun 2011 V Ivanchenko general cleanup - all old deexcitation code removed
37 // 04 Jul 2011 L Pandola removed unused private member
