| 31 | // F.W. Jones, TRIUMF, 03-DEC-96 |
---|
| 32 | // |
---|
| 33 | // This class encapsulates cross section data and interpolations |
---|
| 34 | // from the Geant3/Gheisha routine GHESIG. |
---|
| 35 | // For further comments see G4HadronCrossSections.cc. |
---|
| 36 | // |
---|
| 37 | // Note: this is implemented as a SINGLETON class |
---|
| 38 | // |
---|
| 39 | // 27-MAR-97 FWJ: first version for Alpha release |
---|
| 40 | // 14-APR-97 FWJ: class name changed from G4LCrossSectionData |
---|
| 41 | // to G4HadronicCrossSections |
---|
| 42 | // 14-APR-98 FWJ: rewritten as class G4HadronCrossSections |
---|
| 43 | // and adapted to G4CrossSectionDataSet/DataStore class design. |
---|
| 44 | // 26-JUN-98 FWJ: added elastic/inelastic caching to improve performance. |
---|
| 45 | // 06-NOV-98 FWJ: added first-order correction for low-energy |
---|
| 46 | // inelastic cross sections |
