Abstract
The authors consider the problem of describing theoretically the dynamics of nucleon clustering inside a fissile nucleus. The approach is based on the microscopic modeling of clustering as a new type of collective particle motion. The use of a dynamic clustering algorithm in the region of heavy nuclei requires effective multiparticle interaction to be developed for a distributed microscopic model. Calculations are performed for a double magic cluster that plays an important role in the formation of the second minimum of the fission barrier observed in the multimodal fission of heavy nuclei.
