Abstract:The combined modeling of the excited nuclear fission process is performed taking into account the stochastic nature of the angular momenta carried by the emitted particles. The standard fixed values of the angular momenta are used as well for the comparison. The study shows where the stochastic character is important to be taken into account, and where it is possible to reduce the simulation time by using the fixedvalues of the momenta carried.
