Calculated properties of superheavy nuclei

Ground-state properties of the heaviest nuclei are analyzed within a macros copic-microscopic approach. The main attention is paid to such properties a s deformation, deformation energy, energy of the first rotational state 2() of a nucleus, and the branching ratio of alpha decay to this 2(+) state w ith respect to the decay to the ground state 0(+). The analysis concerns th e problem of experimental confirmation of theoretically predicted deformed shapes of superheavy nuclei situated in the region around the nucleus (270) Hs. A large region of even-even nuclei with proton, Z = 82-128, and neutron , N = 126-190, numbers is considered. (C) 2001 MAIK "Nauka/Interperiodica".
