  We use recently developed method of accurate atomic calculations which
combines linearized single-double coupled cluster method with the configuration
interaction technique to calculate ionisation potentials, excitation energies,
static polarizabilities and valence electron densities for superheavy elements
Uut, Fl and Uup ($Z$=113 to 115) and their ions. The accuracy of the
calculations is controlled by comparing similar calculations for lighter
analogs of the superheavy elements, Tl, Pb and Bi with experiment. The role of
relativistic effects and correlations is discussed and comparison with earlier
calculations is presented.
