Abstract

We use recently developed efficient versions of the configuration interaction method to perform {\em ab initio} calculations of the spectra of superheavy elements seaborgium (Sg, Z=106Z=106), bohrium (Bh, Z=107Z=107), hassium (Hs, Z=108Z=108) and meitnerium (Mt, Z=109Z=109). We calculate energy levels, ionization potentials, isotope shifts and electric dipole transition amplitudes. Comparison with lighter analogs reveals significant differences caused by strong relativistic effects in superheavy elements. Very large spin-orbit interaction distinguishes subshells containing orbitals with a definite total electron angular momentum jj. This effect replaces Hund's rule holding for lighter elements.
