Term energies, ionization energies, inner-shell energy differences and oscillator strengths for some atoms and ions have been calculated within the framework of H-F with relativistic corrections. The wave functions and relativistic mass-velocity and Darwin energy corrections have been obtained using the HF86 code. For oscillator strength computations, the gf-Values code and the Reduced Matrix Elements code are used. Comparisons with similar calculations and/or experiment are presented.
