✦ Synopsis
Shell effects in the masses of heaviest nuclei, most of which are well deformed, are studied. The main attention is paid to the study of the high-multipolarity components, flo and f18 °, of the equilibrium deformation of these nuclei, and of the contribution of these components to the masses of the nuclei. Even-even nuclides with proton numbers Z = 82 -120 and neutron mlmbers N = 126 -190 are considered.

Mechanism behind the relation between shell structure and stability of superheavy nuclei is discussed. The discussion is concentrated on the static spontaneous-fission barriers, calculated for these nuclei within a macroscopic-microscopic model.
Superdeformation studies in lsg '191'192T1 at Gammasphere are discussed. New results on 191T1 are the observation of interband transitions between the signature partner E2 bands and the measurement of an average quadrupole moment (Q0 = 18 4-1 eb) for these superdeformed structures. These data enable
