Investigation of Alpha-Decay Properties of Superheavy Nuclei within RMF Models

This study examined the alpha-decay characteristics of specific superheavy nuclei using the Relativistic Mean Field model. Ground-state characteristics, including binding energies, deformation parameters, charge radii, and two-neutron separation energies, were effectively assessed and utilized to examine nuclear stability. The findings demonstrate enhanced shell stabilization with an increasing proton number, alongside a progressive shift towards spherical nuclear configurations. The computed alpha-decay energies diminish systematically across the analyzed nuclei, resulting in a concomitant increase in alpha-decay half-lives. The uniformity among several half-life equations illustrates the dependability of the derived predictions. The nucleus ²⁹⁶120 was recognized as the most stable configuration among the chosen nuclei, demonstrating the minimal Qα value and the protracted anticipated half-life. The study validates the efficacy of the RMF technique in characterizing the structure and decay properties of superheavy nuclei. The results offer theoretical validation for increased stability around Z = 120 and aid in the pursuit of identifying the island of stability and the synthesis of novel superheavy elements.
