---|
| 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 |
