Abstract. Extended macroscopic-microscopic calculations of the potential-energy surfaces (PES) in a 4D Fourier deformation-parameter space have been performed for 170-204Pt, 172-218Hg, and 174-220Pb isotopes. Several local minima in the PES corresponding to the ground-state and shape isomers were found. Axial and non-axial electric quadrupole moments as well as moments of inertia were evaluated in these minima.
