# Electron and Nucleon Localization Functions of Oganesson: Approaching the Thomas-Fermi Limit.

@article{Jerabek2018ElectronAN, title={Electron and Nucleon Localization Functions of Oganesson: Approaching the Thomas-Fermi Limit.}, author={Paul Jerabek and Bastian Schuetrumpf and Peter Schwerdtfeger and Witold Nazarewicz}, journal={Physical review letters}, year={2018}, volume={120 5}, pages={ 053001 } }

Fermion localization functions are used to discuss electronic and nucleonic shell structure effects in the superheavy element oganesson, the heaviest element discovered to date. Spin-orbit splitting in the 7p electronic shell becomes so large (∼10 eV) that Og is expected to show uniform-gas-like behavior in the valence region with a rather large dipole polarizability compared to the lighter rare gas elements. The nucleon localization in Og is also predicted to undergo a transition to the… Expand
