Abstract:

Thenuclear dynamical deformation, the fusion probability and the evaporationresidue (ER) cross sections for the synthesis of superheavy nuclei are studiedwith the di-nuclear system model and the related dynamical potential energysurface. The intrinsic energy and the maximum dynamical deformations for 48Ca+248Cmare calculated. The effect of dynamical deformation on the potential energysurface and fusion is investigated. It is found that the dynamical deformationinfluences the potential energy surface and fusion probability significantly.The dependence of the fusion probability on the angular momentum isinvestigated. The ER cross sections for some superheavy nuclei in 48Cainduced reactions are calculated and it is found that the theoretical resultsare in good agreement with the experimental results.
