Impact of nuclear structure on the production and identification of superheavy nuclei

Abstract

The shell structure of heavy nuclei with Z > 104, which can be produced in actinide-based complete fusion reactions, is studied with a modified two-center shell model. Using the macroscopic-microscopic approach, mass excesses and Qα-values are calculated and compared with available experimental data. The production cross sections of new superheavy nuclei decisively depend on the position of the proton shell closure.
