Spontaneous fission of spherical superheavy nuclei is studied in a mul
tidimensional deformation space. Potential energy, fission barrier and
fission half-life are analyzed. The half-life is studied in a dynamic
al approach. Even-even isotopes of the element 114, with neutron numbe
r N = 174-186, are considered. Alpha-decay half-lives are also given,
for completeness.
