“…Cluster radioactivity is an exotic nuclear decay mode observed in actinides (from 221 Fr to 242 Cm) where a light nucleus ( 14 C, 20 O, 23 F, 24−26 Ne, 28−30 Mg, 32,34 Si) is emitted. Because the heavy-mass residue is always the doubly magic 208 Pb or a nucleus in its neighborhood, this process is also called "lead radioactivity".…”

Self-consistent methods for structure and production of heavy and superheavy nuclei

et al. 2021

Self-consistent methods for the structure of heavy and superheavy nuclei are reviewed. The construction and application of energy-density functionals are discussed. The relationship between the self-consistent methods and microscopic-macroscopic approaches is considered on the mean-field level. The extraction of single-particle potentials from the energy-density functional is described. The isotopic dependence of nucleon distributions and its influence on the nucleus-nucleus interaction is analyzed. As a new additional condition we introduce that the energy-density functional must describe the heights of the Coulomb barriers in nucleusnucleus interaction potentials, thus imposing constraints on the properties of the functional at low matter densities. The self-consistent methods are applied to describe the quasiparticle structure, cluster radioactivity, and fission of the heaviest nuclei. These methods are used to predict the probabilities of β-delayed multi-neutron emission and half-lives of β-decays and electron captures in heavy and superheavy nuclei. The predicted properties of superheavy nuclei are used to estimate the production cross-sections of superheavy nuclei in complete fusion reactions. Contents

“…In general, many theoretical models have been developed and applied to interpret experimental data by estimating the evaporation residue cross section. On one hand, the synthesis mechanism of SHE needs to be elucidated [23][24][25][26][27][28][29][30][31][32][33][34][35]. Various approaches are devoted to calculating the fusion probability of the colliding nuclei, as well as analyzing the distribution of quasifission fragments [28,[36][37][38].…”

The combined dinuclear system (DNS) and statistical model implanted in KEWPIE2 have been used to study the prospects for the synthesis of a superheavy element (SHE) with Z = 119 in the 54 Cr+ 243 Am fusion reaction. The method of calculation has been verified by description of the evaporation residue cross sections measured for the 48 Ca+ 243 Am reaction. The calculated results of the partial and total cross sections for the complete fusion, quasifission, fast fission and evaporation residues formation for both reactions are discussed.

The model for the cold-fusion reactions related to the synthesis of super-heavy nuclei in collisions of heavy projectile-nuclei with 208 Pb target nucleus is discussed. In the framework of this model the production of the compound nucleus by two paths through, the di-nuclear system and the fusion way, are taken into account simultaneously. The formation of the compound nucleus in the framework of the di-nuclear system is related to the transfer of nucleons from the light nucleus to the heavy one. The fusion way is linked to the sequential evolution of the nuclear shape from the system of contacting nuclei to the compound nucleus. It is shown that the compound nucleus is mainly formed by the fusion way in the cold-fusion reactions. The landscape of the potential energy related to the fusion path is discussed in detail. This landscape for very heavy nucleus-nucleus systems has the intermediate state, which is linked to the formation of both the compound nucleus and the quasi-fission fragments. The decay of the intermediate state is taken into account in the calculation of the compound nucleus production cross sections and the quasi-fission cross sections. The values of the cold-fusion cross sections obtained in the model are well agreed with the experimental data.
