Semiempirical Shell Model Masses with Magic Number Z = 126 for Superheavy Elements
A semiempirical shell model mass equation applicable to superheavy elements up to Z = 126 is presented and shown to have a high predictive power. The equation is applied to the recently discovered superheavy nuclei 293 118 and 289 114 and their decay products. 269 Sg has been observed. The α-decay energies vary rather smoothly along the chain. If the above assignments are confirmed, and the dec...
متن کاملApplications of semiempirical shell model masses based on magic proton number Z = 126 to superheavy nuclei
A recently published highly extrapolatable semiempirical shell model mass equation is shown to describe rather well the energies of several seemingly well identified α-decay chains with known end product nuclei observed in super-heavy elements research. The equation is also applied to the interpretation problem of some recent hot fusion-evaporation experiments with unknown end products and seve...
متن کاملShell Structure of the Superheavy Elements
Ground state properties of the superheavy elements (SHE) with 108≤Z≤128 and 150≤N≤192 are investigated using both the Skyrme-Hartree-Fock method with a density-independent contact pairing interaction and the macroscopic-microscopic approach with an average Woods-Saxon potential and a monopole pairing interaction. Detailed analysis of binding energies, separation energies, shell effects, single ...
متن کاملAdsorption Studies with Homologs of Superheavy Elements
In preparation of chemical studies with superheavy elements around Z = 114, the adsorption behavior of these elements and their lighter homologs on different metals has been predicted based on (semi-)empirical models and extrapolations (see e.g. [1, 2]). Adsorption studies with SHE homologs were performed on various metals, especially metals of group 10 and 11 (see e.g. [3]). The experimental r...

A semiempirical shell model mass equation based on magic number Z = 126 and applicable to translead elements with N ≤ 126 is presented. For α-decay energies the equation is shown to have a high predictive power and an rms deviation from the data of about 100 keV. The rms deviations for masses and other mass differences are between about 200 and 300 keV. Recent progress in superheavy elements (S...
