Abstract A configuration interaction approach with a semiempirical model potential for the core was used to study the static and dynamic properties of the alkaline-earth-metal atoms. The alkaline-earth-metal atoms properties determined were the scalar and tensor polarizabilities, the quadrupole moment, some of the oscillator strengths and the dispersion coefficents of the van der Waals intearaction. It was observed that the use of a polarization potential to the experimental binding energy consider the influence of relativistic effects upon the core electron distribution. The resulting polarizabilities, and dispersion parameters for homonuclear pairs of atoms were within 0.1% and within 1-2 % for heavier atoms.
