    "abstract": "Spontaneous-fission half-lives of the heaviest even-even nuclei are evaluated\nand compared with their alpha-decay mode. Calculations of spontaneous-fission\nhalf-lives are performed in the dynamical way with potential energy obtained by\nthe macroscopic-microscopic method and the inertia tensor obtained by the\ncranking approximation. The alpha-decay half-lives are calculated for the same\nregion of nuclei by use of the Viola and Seaborg formula. The ground-state\nproperties such as mean square radii and electric quadrupole moments are also\nstudied. From the analysis of spontaneous-fission half-life values it is found\nthat a peninsula of deformed metastable superheavy nuclei near Z=106 and N=162\nis separated from an island of the spherical superheavy, around the doubly\nmagic nucleus with Z=114 and N=184, by a trench in the vicinity of neutron\nnumber N=170.",
