چکیده

The recent discovery of isotopes with Z=110–111 suggests evidence for (1) a monopole–monopole interaction that does not appear explicitly in Nilsson– Strutinsky mass systematics, and (2) a competition between SU(2) and SU(3) dynamical symmetries that has been predicted for this region. Our calculations suggest that these new isotopes are near spherical, and may represent a true island of superheavy nuclei, but shifted downward in neutron number by these new physical effects.

Ground state properties of the superheavy elements (SHE) with 108≤Z≤128 and 150≤N ≤192 are investigated using both the Skyrme-Hartree-Fock method with a density-independent contact pairing interaction and the macroscopic-microscopic approach with an average Woods-Saxon potential and a monopole pairing interaction. Detailed analysis of binding energies, separation energies, shell effects, single...

Realistic fusion barriers are calculated in a macroscopic-microscopic model for several soft-fusion heavy-ion reactions leading to heavy and superheavy elements. The results obtained in such a realistic picture are very different from those obtained in a purely macroscopic model. For reactions on 208 Pb targets, shell effects in the entrance channel result in fusion-barrier energies at the touc...

A detailed understanding of complete fusion cross sections in heavy-ion collisions requires a consideration of the effects of the deformation of the projectile and target. Our aim here is to show that deformation and orientation of the colliding nuclei have a very significant effect on the fusion-barrier height and on the compactness of the touching configuration. To facilitate discussions of f...
