Ternary clusterization and quadrupole deformation

The deformation-dependence of ternary clusterization of atomic nuclei is investigated. In particular, allowed and forbidden ternary clusterconfigurations are determined for the ground, superdeformed, and hyperdeformed states of some light and heavy nuclei, based on a microscopic (real and effective SU(3)) selection rule. The energetic stability of the clusterizations is also considered. The investigation of exotic nuclear shapes, e.g. superdeformed and hyperdeformed states is one of the most interesting topics in recent nuclear structure studies. The appearance of exotic cluster configurations (or exotic cluster decay) is another issue of utmost interest. The combination of these two problems brings us to an exciting question: what is the interrelation of these two phenomena, i.e. what are the possible clusterizations of nuclear states with exotic shapes. In the present Letter we address this question from the angle of the ternary clusterization. We apply methods which can be generalized to more complicated multicluster-configurations in a straightforward way.The basic concept of this work is that when we try to describe the composition of an atomic nucleus from smaller nuclei (clusters) then we take into account both of the two complementary natural laws, which govern this kind of phenomenon: the energy-minimum principle and the Pauli-exclusion principle. The crucial role of these two rules are obvious: energetically unfavored systems are not likely to appear, and when the building blocks are fermions, like the nucleons of the atomic nuclei, then they follow the exclusion principle. However, the exact role, or * Corresponding author.E-mail address: algora@atomki.hu (A. Algora).relative importance of these two aspects of clusterization among different circumstances are not completely understood yet; the present work is meant to be a contribution to this task. Much attention has been paid to the energetic preference of various cluster-configurations of a nucleus. The methods applied along this line are partly or completely empirical ones, using information gained from the experimental data. Furthermore, most of these works concentrate on the simplest, i.e. binary clusterizations, especially, when the energetic calculation involves (in addition to the experimental binding energies) intercluster potentials, like in the dinuclear system model [1], or in the local potential approach [2]. On the other hand the treatment of the exclusion-principle has to be done microscopically, therefore, apart from the light, or simplest heavy nuclei, it gives rise to large computational difficulties. Due to this fact no systematic studies has been done, and many of the experimentally interesting systems are untouched from this viewpoint.The main point of this Letter is to present a method for the approximative treatment of the exclusion principle, which can be applied both to binary [3] and to ternary (and even to multi) cluster-configurations. The results of these calculations can be combined with those on the energetic sta...

“…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.…”

Abstract. A static scission configuration in cold ternary fission has been considered in the framework of mean field approach. The inverse scattering 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.
