| 33 | // Model implementation for pre-equilibrium decay models in geant4. |
---|
| 34 | // To be used in your physics list, in case you neeed this kind of physics. |
---|
| 35 | // Can be used as a stand-allone model, but also in conjunction with an intra-nuclear |
---|
| 36 | // transport, or any of the string-parton models. |

| 39 | // Modif (03 September 2008) by J. M. Quesada for external choice of inverse |
---|
| 40 | // cross section option.(default OPTxs=3) |
---|
| 41 | // JMQ (06 September 2008) Also external choices have been added for: |
---|
| 42 | // - superimposed Coulomb barrier (if useSICB=true, default false) |
---|
| 43 | // - "never go back" hipothesis (if useNGB=true, default false) |
---|
| 44 | // - soft cutoff from preeq. to equlibrium (if useSCO=true, default false) |
---|
| 45 | // - CEM transition probabilities (if useCEMtr=true, default false) |
