Discovery of the Element With Atomic Number Z = 118 Completing the 7th Row of the Periodic Table

Solid Oganesson via a Many-Body Interaction Expansion Based on Relativistic Coupled-Cluster Theory and from Plane-Wave Relativistic Density Functional Theory

“…Potential Parameters for the Og Trimer Obtained from a Fit of the Ab Initio Data ΔE(3) Calculated on the CCSD(T) Level for the EATM Functional Form, Equation7, along with the Simple Repulsive ATM Potential Parameter C ATM All potential parameters are given in atomic units.…”

A Theoretical Study on the Adsorption Behavior of Element 113 and Its Homologue Tl on a Quartz Surface: Relativistic Periodic DFT Calculations

“…Nowadays, superheavy elements (SHEs) from Z = 104 (Rf) to Z = 118 are known. 1 Study of their physicochemical properties is of high interest and important to prove their position in the Periodic Table defined by the atomic number, Z. Chemical behavior of SHEs may be very much different from that of their lighter homologues in the chemical groups due to increasingly strong relativistic effects on their electron shells.…”

Theoretical study of isotope production in the peripheral heavy-ion collision 136Xe + Pb at 1 GeV/nucleon

“…Various research groups at the several accelerator facilities are trying to produce new elements/isotopes. In some laboratories including GSI, JINR, and RIKEN new elements in between Z=107 (Bohrium-Bh) and Z=118 (Oganesson-Og) were discovered in the period of the years 1981 and 2006 [37]. They are mostly unstable and decay after a short time in milliseconds, therefore they are not directly observed, but their decay chains can be measured.…”
