Abstract: Extensive configuration interaction (CI) wave functions are determined using MCHF method and are used to calculate relativistic and non-relativistic energy levels.Agreement is obtained between the calculated and experimental energy levels.Relativistic and non-relativistic electric dipole,magnetic dipole and electric quadrupole oscillator strengths have also been calculated using the CI wave functions.There is a general agreement between the length form and the velocity form.

Key words: MCHF, radial wave function, oscillator strength
