0030 // History:
0031 // -----------
0032 // 12 Jan 2009   L. Pandola   1st implementation. Migration from EM process
0033 //                            to EM model. Physics is unchanged.
0034 // 23 Oct 2009   L. Pandola   remove un-necessary methods to manage atomic
0035 //                            deexcitation (done by G4VEmModel)
0036 // 01 Jun 2011   V Ivanchenko general cleanup - all old deexcitation code removed
0037 // 04 Jul 2011   L Pandola    removed unused private member
