A new version of the theoretical model and computing code for calculations of the pre- and post-scission light particle spectra and multiplicity distributions, the evaporation residue cross sections, and the fission product yield cross sections has been developed. The most important dynamical effects (nuclear friction and light particle emission at the descent from saddle to scission point) in the decay of heated rotating compound nuclei were included in consideration [1]. The fission characteristics have been calculated for every compound nucleus at excitation energy and angular momentum at the scission point. The contributions from different fission modes including the superasymmetric one, the influence of nuclear shells and charge polarization at scission point, and odd—even effects have been taken into account [2,3]. Monte Carlo simulation procedure was used to model in a natural way the timing of the decay of compound nucleus. The model and calculation code have been tested and used for analysis of heavy ion fusion-fission reactions [1] and light particle induced fission at intermediate energy [2,3].
