N2 - Orbital wavefunctions of a large number of levels Na I, Mg II, Al III and Cl VII have been calculated using a frozen-core Hartree-Fock approximation which includes a nonempirical polarisation potential derived from polarised core orbitals. The calculated ionisation energies are in very good agreement with precise measurements. Electric dipole oscillator strengths derived from the computed wavefunctions and energies are found to be of generally high accuracy.
