Exploring α decay properties in the superheavy region through the double-folding formalism and Skyrme interactions

Abstract

In this study, $\ensuremath{\alpha}$ decay properties of yet unknown nuclei are investigated through the systematic behavior of the parameters of $\ensuremath{\alpha}$-nucleus double-folding (DF) potentials. To calculate DF potentials, the density distributions of the protons and neutrons are being employed by use of the self-consistent Hartree-Fock-Bogoliubov (HFB) calculations based on the SLy4 Skyrme interaction widely used for the $\ensuremath{\alpha}$-emitter systems and the superheavy region. In addition, a new set of effective Skyrme force parameters is presented so that more precise estimations, labeled OMGA, are optimized to describe the ground-state properties of superheavy nuclei with $82\ensuremath{\le}Z\ensuremath{\le}120$. Consequently, a good mass fit and half-lives are thus obtained by the optimized Skyrme force with more consistency with experimental data.
