“…This confirms that a large variety of nuclear large-amplitude collective motions such as bimodal fission 8 , cold binary fission 5,9,10,11,12 , heavy cluster radioactivity 13,14 , and inverse processes, such as subbarier fusion 15 , could belong to the general phenomenon of cold nuclear fragmentation.…”

A static scission configuration in cold ternary fission has been considered in the framework of two mean field approaches. The virial theorems has been suggested to investigate correlations in the phase space, starting from a kinetic equation. The inverse mean field method is applied to solve single-particle Schrödinger equation, instead of constrained selfconsistent Hartree-Fock equations. It is shown, that it is possible to simulate one-dimensional three-center system via inverse scattering method in the approximation of reflectless single-particle potentials.

“…Thus the configuration at the scission point should be described in these cases by very compact shapes, the deformed fragments in their ground states. It was already shown that for cold binary fragmentations, the ground state deformations are a key ingredient for the correct prediction of the most favoured splittings and of the isotopic yields [6,17,18,28]. The cluster model which we used in this paper for calculating the isotopic yields associated with 10 Be-accompanied cold ternary fission, also predicts a large number of favored ternary splittings in which one or both heavier fragments are well deformed in their ground states.…”

“…The first direct observation of cold (neutronless) binary fragmentations in the spontaneous fission of 252 Cf was made [4,5], by using the multiple Ge-detector Compact Ball facility at Oak Ridge National Laboratory, and more recently with the Gammasphere consisting of 72 detectors [5,6].…”

: A new type of decay corresponding to the neutronless 10 Beaccompanied fragmentation of 252 Cf is studied. We employ a cluster model similar to the model used for the description of cluster radioactivity. No preformation factors were considered. The ternary relative isotopic yields were calculated as the ratio of the penetrability of a given ternary fragmentation over the sum of penetrabilities of all possible ternary neutronless fragmentations. The corresponding barriers between the light and heavy fragment and between the 10 Be cluster and the two heavier fragments were computed with the help of a double folding potential generated by M3Y-NN effective interaction and realistic fragment ground state deformations. Also, we studied the influence of the fragment excitation energies on the yields, by including the level densities and the β-stretching of the fragments. The new phenomenon could be experimentally observed by the triple gamma coincidence technique between the fragments and 10 Be.PACS number : 25.85.Ca,27.90.+b

“…Very recently direct experimental evidence was presented for the cold (neutronless) ternary spontaneous fission of 252 Cf in which the third particle is an α-particle [6], or 10 Be [7]. This confirms that a large variety of nuclear large-amplitude collective motions such as bimodal fission [8], cold binary fission [5,9,10,11,12], heavy cluster radioactivity [14,13], and inverse processes, such as subbarier fusion [15], could belong to the general phenomenon of cold nuclear fragmentation.…”
