    "abstract": "We predict a molecular vibrational state in the cold binary fission of\n$^{252}$Cf using a simple decay cluster model. The Hamiltonian of two even-even\nfragments in the pole-pole configuration is built in the same fashion as that\nfor the dinuclear molecule formed in heavy-ions collisions. The interaction\nbetween the two fragments is described by the double-folding M3Y potential. The\nspectrum of the butterfly vibrations is derived and its dependence on fragments\ndeformation and mass-assymetry is discussed. Some experimental implications are\ncommented.",
