Nuclear ground-state properties of Z=122 superheavy nuclei

A systematic investigation of the nuclear structure and decay properties of $Z=122$ superheavy nuclei in the range of 160≤ N ≤ 200 is carried out within the framework of the self-consistent Hartree-Fock-Bogoliubov approach, based on a Skyrme energy density functional. Ground-state properties, including binding energies, separation energies, nuclear radii, and nuclear deformations, are evaluated to explore possible signatures of shell closures and magic numbers in this region. Additionally, α-decay half-lives using the Unified Fission Model, incorporating a modified Woods-Saxon potential for the nuclear interaction and the spontaneous fission half-lives are also calculated for comparison. The theoretical predictions exhibit good agreement with previous studies, supporting the validity of the adopted approach.
