Multiconfiguration Dirac-Fock (MCDF) method was employed to calculate the ionization potentials, ionic radii, excitation energies and oscillator strengths for neptunium ions. In the calculations, main valence correlation effects, Breit interaction and QED effects were taken into account. The good consistency with other available theoretical values demonstrates the validity of the present calculations. These theoretical results therefore can be used to predict some physicochemical properties of Np and its oxides.
