Fission 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 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-residues Produced in the Spallation Reaction
Fission fragments from 1 A GeV U projectiles irradiating a hydrogen target were investigated by using the fragment separator FRS for magnetic selection of reaction products including ray-tracing and E-ToF techniques. The momentum spectra of identi ed fragments were analysed to provide isotopic production cross sections, ssion-fragment velocities and recoil momenta of the ssioning parent nuclei....

related to the relatively small number of total ions utilized for determining the mass spectra. CONCLUSION It would be a significant advance if the mass resolution of 1500 obtained with inorganic specimens could be retained with nonvolatile and thermally labile organic specimens as well as obtaining the structurally significant fragment ion signals. This advance will require more detailed studi...
