# Ionization potentials and electron affinity of oganesson

@inproceedings{Guo2021IonizationPA, title={Ionization potentials and electron affinity of oganesson}, author={Yangyang Guo and Luk'avs F. Pavsteka and Ephraim Eliav and Anastasia Borschevsky}, year={2021} }

We present high accuracy relativistic coupled cluster calculations of the first and second ionization potentials and the electron affinity of the heaviest element in the Periodic Table, Og. The results were extrapolated to the basis set limit and augmented with the higher order excitations (up to perturbative quadruples), the Breit contribution, and the QED self energy and vacuum polarisation corrections. We have performed an extensive investigation of the effect of the various computational…
