29 // History:
30 // -----------
31 // 15 Feb 2010 L. Pandola 1st implementation.
32 // 18 Mar 2010 L. Pandola Removed GetAtomsPerMolecule(), now demanded
33 // to G4PenelopeOscillatorManager
34 // 24 May 2011 L. Pandola Renamed (make v2008 as default Penelope)
35 // 10 Jun 2011 L. Pandola Migrated to the new AtomDeexcitation interface
36 // 09 Oct 2013 L. Pandola Migration to MT
