Abstract

The existence of highest proton numbers at which the nuclear landscape cease to ex- ist, the end of the periodic table of elements and the limits of the existence of the nu- clei are some of the difficult questions to answer. To explore those questions, we in- vestigated hyperheavy nuclei (Z ≥ 126) using covariant density functional theory. We demonstrate the existence of three regions of spherical hyperheavy nuclei centered around (Z ∼ 138, N ∼ 230), (Z ∼ 156, N ∼ 310) and (Z ∼ 174, N ∼ 410). Also, we explored other properties of hyperheavy nuclei such as octupole deformation, alpha decay half lives, chemical potential, etc.
