Abstract

In this process a heavy or superheavy nucleus spontaneously breaks into four, five, or six nuclei of which two are asymmetric or symmetric heavy fragments and the others are light clusters, e.g., α particles, 10Be,14C,20O, or combinations of them. Examples are presented for the two-, three-, and four-cluster accompanied cold fission of 252Cf and 262Rf, in which the emitted clusters are 2α, α+6He, α+10Be, α+14C, 3α, α+6He+10Be, 2α+6He, 2α+8Be, 2α+14C, and 4α. A comparison is made with the recently observed 252Cf cold binary fission, and cold ternary (accompanied by α particle or by 10Be cluster). The strong shell effect corresponding to the doubly magic heavy fragment 132Sn is emphasized. The most favorable mechanism of such a decay mode should be the emission from an elongated neck formed between the two heavy fragments.
