摘要

在扩展的vicsek型集体模型框架内考虑了裂变碎片形成的理论描述问题。非平均场方法是基于对原子核聚簇现象的微观模拟，这是由于粒子之间的短程相互作用而聚集的现象。对重核和超重核多模态裂变实验中观察到的208Pb团簇进行了数值模拟。

Model of Nucleon Clustering and Fragment Formation in Fission of Heavy Nuclei

The problem of theoretical description of the formation of fission fragments was considered 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 ²⁰⁸Pb cluster, which is observed experimentally in the multimodal fission of heavy and superheavy nuclei.
