| 36 | // 05.07.2006 V.Ivanchenko define process by particle name; |
---|
| 37 | // fix problem of initialisation of HP |
---|
| 38 | // 24.07.2006 V.Ivanchenko add G4NeutronHPElasticData |
---|
| 39 | // 10.08.2006 V.Ivanchenko separate neutrons from other particles |
---|
| 40 | // 17.11.2006 V.Ivanchenko do not redefine G4HadronElastic default parameters |
---|
| 41 | // 19.02.2007 V.Ivanchenko set QModelLowLimit and LowestEnergyLimit to zero |
---|
| 42 | // 19.02.2007 A.Howard set QModelLowLimit and LowestEnergyLimit to zero |
---|
| 43 | // for neutrons |
---|
| 44 | // 06.03.2007 V.Ivanchenko use updated interface to G4UElasticCrossSection |
