3 | The evaporation model algorithm consists |
---|
4 | from repeating steps of binary break-ups of |
---|
5 | the excited nuclear fragments: |
---|
6 | \begin{enumerate} |
---|
7 | \item Create a nuclear fragment: assign atomic mass number $A$, electrical |
---|
8 | charge $Z$, fragment four vector $P_0$, fragment excitation energy $E^{*}$ and |
---|
9 | fragment angular momentum $\vec{L}_0$; |
---|
10 | \item Calculate the probabilities of break-up channels and |
---|
11 | sample a channel; |
---|
12 | \item Sample evaporated fragment $b$ kinetic energy at rest of decaying fragment; |
---|
13 | \item Assuming isotropical evaporated fragments distribution, sample |
---|
14 | its flay off angles at rest of decaying fragment $b$; |
---|
15 | \item boost the evaporated and residual fragment momenta into observer frame. |
---|
16 | \item Calculate residual fragment atomic mass number $A_f$, electrical |
---|
17 | charge $Z_f$, fragment four vector $P_f$, fragment excitation energy |
---|
18 | $E_f^{*}$ and |
---|
19 | fragment angular momentum $\vec{L}_f$; |
---|
20 | \item Repeat this procedure starting from step (2) |
---|
21 | until no more fragment (the probabilities of break-up channels |
---|
22 | equal zero) can be evaporated. |
---|
23 | \end{enumerate} |
