“…The nucleus 294 Og, produced in Dubna (Oganessian et al, 2006) with a ∼0.5 picobarn cross section, marks the current limit of nuclear charge and mass. It decays to 290 Lv by α-decay with a half-life of 0.58 ms (Brewer et al, 2018), which is currently too short for "atom-at-a-time" chemical studies. As a result, computing its electronic and nuclear structure is the only option currently available to study such elements.…”

Colloquium : Superheavy elements: Oganesson and beyond

et al. 2019

During the last decade, six new superheavy elements were added into the seventh period of the periodic table, with the approval of their names and symbols. This milestone was followed by proclaiming 2019 the International Year of the Periodic Table of Chemical Elements by the United Nations General Assembly. According to theory, due to their large atomic numbers, the new arrivals are expected to be qualitatively and quantitatively different from lighter species. The questions pertaining to superheavy atoms and nuclei are in the forefront of research in nuclear and atomic physics, and chemistry. This Colloquium offers a broad perspective on the field and outlines future challenges. References

“…Introduction -The region of superheavy nuclei (Z ≥ 104) is one of the frontiers of modern nuclear physics. The heavy-ion fusion experiments have been able to push the boundaries of the nuclear chart all the way to 294 118 Og 176 [1][2][3], and new efforts are underway to increase production rates of superheavy systems [4][5][6][7]. Due to the large number of nucleons, these nuclei push the limits of nuclear structure models and are expected to answer key questions pertaining to nuclear and atomic physics, astrophysics, and chemistry [8][9][10][11].…”

Cluster radioactivity of Og176118294

et al. 2019

According to theory, cluster radioactivity becomes an important decay mode in superheavy nuclei. In this work, we predict that the strongly-asymmetric fission, or cluster emission, is in fact the dominant fission channel for 294 118 Og176, which is currently the heaviest synthetic isotope known. Our theoretical approach incorporates important features of fission dynamics, including quantum tunneling and stochastic dynamics up to scission. We show that, despite appreciable differences in static fission properties such as fission barriers and spontaneous fission lifetimes, the prediction of cluster radioactivity in 294 118 Og176 is robust with respect to the details of calculations, including the choice of energy density functional, collective inertia, and the strength of the dissipation term.

“…To search for the optimal condition of the superheavy nuclei production, various experiments have been performed to study the entrance channel effect on the evaporation residual cross section [61][62][63][64][65]. Recently, the isospin effect of the target nucleus on the evaporation residue cross section has been explored [66][67][68]. Some laboratories have also attempted to synthesize the Z = 119 and 120 superheavy elements by using hot fusion [69,70].…”

Fusion Dynamics of Low-Energy Heavy-Ion Collisions for Production of Superheavy Nuclei

One of the major motivations for low-energy heavy-ion collision is the synthesis of superheavy nuclei. Based on the following two main aspects, various theoretical and experimental studies have been performed to explore the fusion dynamical process of superheavy nuclei production. The first reason is to elucidate and analyze the synthesis mechanism of superheavy nuclei; the other is to search the favorable incident energy and the best combination of projectile and target to produce new superheavy elements and isotopes of superheavy elements.
