Abstract We investigate the effects of higher-order deformations ( $\lambda=4,6,8,$?> and 10) on ground state properties superheavy nuclei (SHN) near doubly magic deformed nucleus $^{270}{\rm{Hs}}$?> using multidimensionally-constrained relativistic mean-field (MDC-RMF) model with five effective interactions: PC-PK1, PK1, NL3 * , DD-ME2, PKDD. The include large energy ...

We systematically study the nuclear level densities of superheavy nuclei, including odd systems, using single-particle energies obtained with Woods-Saxon potential diagonalization. applied minimization over many deformation parameters for global minima-ground states, and ``imaginary water flow'' technique on a many-deformation energy grid saddle points, nonaxial shapes. The density are calculat...

The formation of $\ensuremath{\alpha}$ particles on nuclear surfaces has remained a fundamental problem since the dawn physics. This $\ensuremath{\alpha}$-particle strongly affects $\ensuremath{\alpha}$-decay lifetimes heavy and superheavy elements, level scheme light nuclei, synthesis elements in stars. However, despite its importance, medium-mass nuclei is seldom investigated. Based $^{48}\ma...

The production cross sections of superheavy nuclei with charge numbers $114-117$ are predicted in the $(5-9)n$-evaporation channels $^{48}$Ca-induced complete fusion reactions for future experiments. estimates synthesis capabilities based on a uniform and consistent set input nuclear data provided by multidimensional macroscopic-microscopic approach. contributions various factors to final secti...

The fusion dynamics of the formation superheavy nuclei were investigated thoroughly within dinuclear system model. Monte Carlo approach was implemented in nucleon transfer process to include all possible orientations, at which is assumed be formed touching configuration fragments. production cross sections Cn, Fl, Lv, Ts, and Og calculated compared with available data from Dubna. evaporation re...

Decaying superheavy particles can be produced by Topological Defects or, in case they are quasistable, as relics from the early Universe. The decays of these particles can be the sources of observed Ultra High Energy Cosmic Rays (E ∼ 10 − 10 GeV ). The Topological Defects as the UHE CR sources are critically reviewed and cosmic necklaces and monopole-antiminopole pairs are identified as most pl...

Superheavy elements owe their existence exclusively to nuclear shell effects which stabilize them against spontaneous fission (SF). Theoretical predictions locate the center of stability at the hypothetical doubly-magic spherical nucleus with Z=114 and N=184 [1]. Calculations with the inclusion of higher orders of deformation [2] suggest the ground state shell correction energy of deformed nucl...

Predictions of the interaction of the superheavy elements with various surfaces are essential for their identification and separation. Recently, we have predicted the adsorption properties of the superheavy element 112 on inert surfaces [1]. The calculations were performed using the fully relativistic Dirac-Coulomb Hamiltonian combined with the coupled cluster method. The accuracy of the result...
