Formatted abstract
Semiempirical model of van de Waals coefficients, C6, C 8 and C10 was developed for the estimation of alkali-metal and alkaline-earth-metal atoms. Comparision of the dispersion coefficients and relativistic many-body perturbation theory (MBPT) reveals that the method is capable of achieving a level of accuracy as compared to more computationaly intensive MBPT approach. The polarization parameters were computed from their respective oscillator strength sum-rules with the dipole, quadrapole, and octupole oscillator strengths from the ground state. The use of the constrained sum-rules to determine oscillator strength value distributions for the core electrons was also discussed.
