The results of ab initio calculation of energies,
hyperfine structure constants and static polarizabilities
for several low-lying levels of barium are reported. The effective
Hamiltonian for the valence electrons 
has been constructed in
the frame of CI+MBPT method and solutions of many electron equation
were found. Using the wave functions
obtained the hyperfine structure constants and static polarizabilities
were calculated.
