First ionization energies agree with the experiment at the level of ~10 mH or less. Calculations with similar accuracy are expected to provide information required for developing the proposed quasiparticle-DFT method.Proceedings of 'The 6th Japan-Italy symposium on Heavy Ion Physics', Mito, Japan, Nov. 2008Chemical PhysicsNuclear Theorytext
