Heaviest nuclei from 48Ca-induced reactions
TLDR
In this article, the experimental investigation of the decay properties of the heavy nuclei is presented, and the obtained results are discussed in the context of the theoretical predictions about the island of stability of the hypothetical superheavy elements.Abstract:
After a brief introduction of the role of shell effects in determining the limiting nuclear masses, the experimental investigation of the decay properties of the heaviest nuclei is presented. For the production of superheavy nuclides fusion, reactions of heavy actinide nuclei with 48Ca-projectiles have been used. The properties of the new nuclei, the isotopes of elements 112–118, as well as of their decay products, together with the known data for the light isotopes with Z ≤ 113, give evidence of the significant increase of the stability with the neutron number of the heavy nucleus. The obtained results are discussed in the context of the theoretical predictions about the 'island of stability' of the hypothetical superheavy elements.read more

Shell effects in nuclear masses and deformation energies
TL;DR: In this paper, the authors calculate the shell-model correction to the liquid drop energy of the nucleus as a function of the occupation number and deformation, and show a strong correlation between the shell correction and nucleon level density at the Fermi energy.
