Model of nucleon clustering and fragment formation in heavy nuclei fission

We considered the problem of theoretical description of the fission fragment formation within the framework of an extended Vicsek-type collective model. The non-mean-field approach is based on microscopic modeling of the nucleon clustering as a phenomenon of particle aggregation due to short-range mutual interaction. Numerical computer simulations were carried out for the Pb cluster, observed experimentally in the multimodal fission of heavy and superheavy nuclei.
