31 | // Class Description |
---|
32 | // Model implementation for pre-equilibrium decay models in geant4. |
---|
33 | // To be used in your physics list, in case you neeed this kind of physics. |
---|
34 | // Can be used as a stand-allone model, but also in conjunction with an intra-nuclear |
---|
35 | // transport, or any of the string-parton models. |
---|
36 | // Class Description - End |
---|
37 | // |
---|
38 | // Modified: |
---|
39 | // 03.09.2008 J.M.Quesada added external choice of inverse |
---|
40 | // cross section option.(default OPTxs=3) |
---|
41 | // 06.09.2008 J.M.Quesada 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) |
---|
46 | // 30.10.2009 J.M.Quesada CEM transition probabilities are set as default |
---|
47 | // 20.08.2010 V.Ivanchenko Cleanup of the code - changed data members and inline methods |
