Fusion Hindrance and the Role of Shell Effects in the Superheavy Mass Region
We present the first attempt of the systematical investigation about the effects of shell correction energy for dynamical processes, which include fusion, fusion-fission and quasi-fission processes. In the superheavy mass region, for the fusion process, the shell correction energy plays a very important role and enhances the fusion probability, when the colliding partner has strong shell struct...

We present the first attempt of systematically investigating the effects of shell correction energy for a dynamical process, which includes fusion, fusion-fission and quasi-fission processes.

متن کاملDynamical approach to heavy ion-induced fission
Deep inelastic collisions (DICs) can compete strongly with fusion in collisions of heavy nuclei. However, standard coupled-channels calculations do not take DIC process into account. As a result, calculations have been shown to overestimate the fusion cross-section and thus lead to a discrepancy between experimental data and theoretical calculations, particularly at energies above the fusion ba...
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...
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...
