| 3 | \hspace{1.0em} The GEANT4 precompound model is considered as an extension |
---|
| 4 | of the hadron kinetic model. It gives a possibility to extend the low |
---|
| 5 | energy range of the hadron kinetic model for |
---|
| 6 | nucleon-nucleus inelastic collision and it provides a "smooth" transition |
---|
| 7 | from kinetic stage of reaction described by the hadron kinetic model to |
---|
| 8 | the equilibrium stage of reaction described by the equilibrium deexcitation |
---|
| 9 | models. |

---|
| 11 | The initial information for calculation of pre-compound |
---|
| 12 | nuclear stage consists from the atomic mass number $A$, charge $Z$ of residual |
---|
| 13 | nucleus, its four momentum $P_0$, |
---|
| 14 | excitation energy $U$ and number of |
---|
| 15 | excitons $n$ equals the sum of number of particles $p$ (from them $p_Z$ |
---|
| 16 | are charged) and number of holes $h$. |
---|
| 17 | |
---|
| 18 | At the preequilibrium stage of reaction, we following the \cite{GMT83} approach, |
---|
| 19 | take into account all |
---|
| 20 | possible nuclear transition the number of excitons $n$ with $\Delta n = |
---|
| 21 | +2, -2, 0$ \cite{GMT83}, which defined by transition probabilities. |
---|
| 22 | Only emmision of neutrons, protons, deutrons, thritium and helium nuclei |
---|
| 23 | are taken |
---|
| 24 | into account. |
