Abstract. A covariant energy density functional, adjusted to nuclear matter equation of state and empirical masses of deformed nuclei, is applied to study shapes of superheavy nuclei. Self-consistent mean field calculations predict a variety of spherical, axial and triaxial shapes of long lived superheavy nuclei. Alpha decay energies and half lives are compared with available experimental information. A microscopic quadrupole collective hamiltonian, based on the relativistic energy density functional, is used to study the effect of explicit treatment of collective correlations in the calculations of Qα values and half lives.
