Nuclear molecules in ternary fission

Abstract

Experimental results on particle accompanied cold fission of 252Cf suggest the existence of a short-lived quasi-molecular state. Within our three-center phenomenological model, described in this paper, we found a possible explanation based on a new minimum in the deformation energy at a separation distance very close to the touching point. Half-lives of some quasimolecular states which could be formed in 10Be accompanied fission of 236U, 236Pu, 246Cm, 252Cf, 252,256Fm, 256,260No, and 262Rf are roughly estimated.
