34 // Modified:
35 // 21.03.2007 V.Ivanchenko Use G4BGGNucleonElasticXS and G4BGGPionElasticXS;
36 // Reduce thresholds for HE and Q-models to zero
37 // 03.06.2010 V.Ivanchenko cleanup constructors and ConstructProcess method
38 // 29.07.2010 V.Ivanchenko rename this class from G4HadronHElasticPhysics to
39 // G4HadronElasticPhysics, old version of the class
40 // is renamed to G4HadronElasticPhysics93
