Prediction of Atomic Properties of Bi and Element 115

In this work, we perform fully relativistic benchmark calculations of polarizabilities ( ), ionization potentials (IP), and electron affinities (EA) of element 115 and its lighter homologue, Bi. These properties are important for prediction of adsorption enthalpy (!Hads) of the two elements on inert surfaces. Knowledge of !Hads is required in order to guarantee the transport of the newly produced element from the target chamber to the chemistry set up. This is the first benchmark calculation of the polarizability of these elements. Calculations of polarizabilities were performed using the DIRAC08 package [1], employing the finite field approach. In the Dirac-Coulomb (DC) ab initio method, the many-electron relativistic Dirac-Coulomb Hamiltonian
