Resonance Energies, Absorption Oscillator Strengths and Ionization Potentials for the Element Hassium (Z= 108)

On the basis of successfully predicting low-lying energy levels for the element fermium (Z = 100), we calculate the resonance energies, absorption oscillator strengths and the first ionization potential of the element hassium (Z = 108) by taking important relativistic and improved electron correlation effects into account using the multiconfiguration Dirac–Fock method. These calculations are carried out with the aim of assisting experimental investigations of hassium.
