Abstract
The results of ab initio calculation of energies, hyperfine structure const ants and static polarizabilities for several low-lying levels of barium are reported. The effective Hamiltonian for the valence electrons H-eff has be en constructed in the frame of CI+MBPT method and solutions of many electro n equation H(eff)Phi(n) = E(n)Phi(n) were found. Using the wave functions o btained the hyperfine structure constants and static polarizabilities were calculated.
