Nuclear shell effect and collinear tripartition of nuclei
Abstract
A possibility of formation of the three reaction products having comparable masses at the spontaneous fission of Cf is theoretically explored. This work is aimed to study the mechanism leading to observation of the reaction products with masses 136---140 and 68---72 in coincidence by the FOBOS group in JINR. The same type of ternary fission decay has been observed in the reaction U(n,fff). The potential energy surface for the ternary system forming a collinear nuclear chain is calculated for the wide range of mass and charge numbers of constituent nuclei. The results of the PES for the tripartition of Cf(sf,fff) shows, that we have favorable dynamical conditions for the formation of fragments with mass combinations of clusters Ni with Sn and with missing cluster Ca.
