3 | \hspace{1.0em}The Monte Carlo procedure of calculation of characteristics of |
---|
4 | fission fragments can be outlined as follows: |
---|
5 | \begin{itemize} |
---|
6 | \item Select fission mode (symmetric or asymmetric). |
---|
7 | Sample atomic number $A_f$ of a fission |
---|
8 | fragment according to experimentaly defined distribution, which consists |
---|
9 | from the "symmetrical" and "asymmetrical" parts; |
---|
10 | \item For choosen $A_f$ randomly in accordance with |
---|
11 | Gaussian distribution and the experimentaly defined |
---|
12 | dispersion and average |
---|
13 | select the fragment charge $Z_f$; |
---|
14 | \item For |
---|
15 | choosen $A_f, Z_f$ sample |
---|
16 | the kinetic energy of fragments |
---|
17 | according to the Gaussian |
---|
18 | distribution |
---|
19 | with experimentaly defined average values |
---|
20 | and dispersions; |
---|
21 | \item Applying energy conservation and using fragment ground state masses |
---|
22 | calculate excitation energy of fragments and share it between fragments |
---|
23 | assuming that fragments have equal temperatures; |
---|
24 | \item Calculate absolute value of the c.m. |
---|
25 | fragment momentum (non-relativistic kinematics |
---|
26 | is used) and sample fragment flay off angles assuming isotropical |
---|
27 | angular distribution of fragments; |
---|
28 | \item Perform evaporation for the excited fragments. |
---|
29 | \end{itemize} |
