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., particles, or combinations of them. Examples are presented for the two-, three-, and four-cluster accompanied cold fission of and in which the emitted clusters are and A comparison is made with the recently observed cold binary fission, and cold ternary (accompanied by particle or by cluster). The strong shell effect corresponding to the doubly magic heavy fragment 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.
