The study of superheavy nuclei constitutes one of the most demanding and intriguing domains of contemporary nuclear physics. The synthesis of elements beyond uranium has greatly extended the limits of the nuclear chart and offered important insights into the behavior of nuclear matter under extreme conditions. Superheavy nuclei are defined by elevated proton counts, wherein the intense Coulomb repulsion among protons often leads to nuclear instability. Quantum shell effects can confer further stabilization, resulting in the prediction of a "island of stability," where specific superheavy nuclei may exhibit comparatively extended half-lives. Comprehending the structural characteristics and stability processes of these nuclei is a primary goal of both theoretical and experimental nuclear studies. This study examines the ground-state features of specific superheavy nuclei using Relativistic Mean Field (RMF) theory. The RMF model has become one of the most effective microscopic methods for elucidating nuclear structure throughout the nuclear chart, owing to its inherent integration of relativistic effects and spin-orbit interactions. Ground-state observables such as binding energies, quadrupole deformation parameters, charge radii, neutron and proton density distributions, and neutron skin thickness are carefully examined for superheavy isotopes within the proton number range Z = 112–126. Calculations utilize a recognized RMF parameter set, and the resultant nuclear features are analyzed to discern shell closures, deformation effects, and potential areas of increased stability. The research indicates substantial shell stabilization at anticipated magic numbers and highlights the essential influence of deformation on the equilibrium configurations of superheavy nuclei. The computed observables suggest increased stability at neutron number N = 184, corroborating theoretical expectations about the presence of an island of stability. The results enhance comprehension of the structure and evolution of superheavy nuclei and offer significant theoretical direction for forthcoming experimental endeavors focused on synthesizing new elements and examining the boundaries of nuclear existence.
KEYWORDS
This study analyzed the ground-state properties and stability features of several superheavy nuclei using the Relativistic Mean Field approach. The research concentrated on nuclei with a proton number of Z = 120 and neutron values between N = 172 and N = 186. Ground-state observables, including binding energy, charge radius, proton and neutron radii, neutron skin thickness, quadrupole deformation parameters, two-neutron separation energies, and shell gap indicators, were thoroughly examined. The findings indicated that binding energies rise with the increase in neutron number, reaching peak values at N = 184, which signifies improved nuclear stability. The charge radii exhibited a progressive increase with mass number, indicating the anticipated expansion of nuclear dimensions. The deformation study indicated a shift from moderately distorted geometries to nearly spherical configurations at N = 184, implying the existence of a shell closure.
