Superheavy elements and the upper limit of the periodic table: early speculations
Artificially produced chemical elements heavier than uranium have been known for more than seventy years and the number of superheavy elements continues to grow. Presently 26 transuranic elements are known. This paper examines the earliest scientific interest in the very heavy elements and the related question of an upper limit of the periodic system. In the period from the 1880s to the early 1...
متن کامل0 Mean – Field Models and Superheavy Elements
We discuss the performance of two widely used nuclear mean-field models, the relativistic mean–field theory (RMF) and the non-relativistic Skyrme–Hartree–Fock approach (SHF), with particular emphasis on the description of superheavy elements (SHE). We provide a short introduction to the SHF and RMF, the relations between these two approaches and the relations to other nuclear structure models, ...
متن کاملChemistry of the superheavy elements.
The quest for superheavy elements (SHEs) is driven by the desire to find and explore one of the extreme limits of existence of matter. These elements exist solely due to their nuclear shell stabilization. All 15 presently 'known' SHEs (11 are officially 'discovered' and named) up to element 118 are short-lived and are man-made atom-at-a-time in heavy ion induced nuclear reactions. They are iden...
متن کاملChemistry of superheavy elements.
The number of chemical elements has increased considerably in the last few decades. Most excitingly, these heaviest, man-made elements at the far-end of the Periodic Table are located in the area of the long-awaited superheavy elements. While physical techniques currently play a leading role in these discoveries, the chemistry of superheavy elements is now beginning to be developed. Advanced an...
متن کاملAn upper limit to the electric dipole moment of the neutron from lattice QCD
Presented the talk. is odd under both of them. This breaking can produce a nonzero value of dn, the electric dipole moment of the neutron [1], dn ≈ 8 · 10 θe · cm. The experimental upper limit is [2] dn|exp < 6 · 10e · cm which implies θ < ∼10. This is a small number and its smallness is not protected by any known symmetry. An alternative possibility for having dn 6= 0 could be a spontaneous br...
