---|
| 36 | // It includes all Physics Routines from Geant3, |
---|
| 37 | // relevant for simulation of hadronic processes |
---|
| 38 | // above approx. 20 GeV incident momentum. |
---|
| 39 | // Not included are the Physics Routines for |
---|
| 40 | // stopping particles, the low energy neutron |
---|
| 41 | // slowing down description and the low energy |
---|
| 42 | // nuclear reactions a(A,A')b. |
---|
| 43 | // All routines pass the compiler and give |

---|
| 45 | // A statistically significant comparison |
---|
| 46 | // with GEANT3 and experimental data has |
---|
| 47 | // still to be done. |
