Entrance-channel potentials in the synthesis of the heaviest nuclei
Entrance-channel potentials in nucleus-nucleus collisions, relevant for the synthesis of superheavy elements, are systematically studied within a semi-microscopic approach, where microscopic nuclear densities of the colliding spherical or deformed nuclei are used in semi-classical expressions of the energydensity functional. From experimental data on fusion windows evidence is found that the ex...
متن کاملFission barriers of compound superheavy nuclei.
The dependence of fission barriers on the excitation energy of the compound nucleus impacts the survival probability of superheavy nuclei synthesized in heavy-ion fusion reactions. In this work, we investigate the isentropic fission barriers by means of the self-consistent nuclear density functional theory. The relationship between isothermal and isentropic descriptions is demonstrated. Calcula...

The Q value and optimal exciting energy of the hypothetical superheavy nuclei in cold fusion reaction are calculated with relativistic mean field model and semiemperical shell model mass equation(SSME) and the validity of the two models is tested. The fusion barriers are also calculated with two different models and reasonable results are obtained. The calculations can give useful references fo...
متن کاملDissipation-fluctuation dynamics of fusion-fission reactions and synthesis of superheavy elements
Dynamical treatments of fission processes are briefly reviewed with an emphasis on the strong dissipation or friction for collective motions of nuclei in high excitation. The theories are applied to synthesis of superheavy elements. Characteristic features of formation and surviving are discussed with reference to possible incident channels. Theoretical prediction are presented on favorable inc...
متن کاملPossibilities for Synthesis of New Superheavy Nuclei Using Stable Beams and Stable or Long-Lived Targets
In our previous article [1], we presented a simple phenomenological model for the description of production cross sections of superheavy nuclei in a wide range of excitation energies including cold, warm and hot fusion. The model assumes that the fusion hindrance, observed in cold fusion reactions where only one neutron is emitted prior to the formation of evaporation residue (ER), can be expla...
