0029 // History:
0030 // -----------
0031 // 15 Feb 2010   L. Pandola   1st implementation.
0032 // 18 Mar 2010   L. Pandola   Removed GetAtomsPerMolecule(), now demanded
0033 //                            to G4PenelopeOscillatorManager
0034 // 24 May 2011   L. Pandola   Renamed (make v2008 as default Penelope)
0035 // 10 Jun 2011   L. Pandola   Migrated to the new AtomDeexcitation interface
0036 // 09 Oct 2013   L. Pandola   Migration to MT
