Abstract

The modes of decay for the even-even isotopes of superheavy nuclei of Z = 118 and 120 with neutron number 160 ≤ N ≤ 204 are investigated in the framework of the axially deformed relativistic mean field model. The asymmetry parameter η and the relative neutron-proton asymmetry of the surface to the center (R_η) are estimated for the ground state density distributions of the nuclei. We suggest that the resulting asymmetry parameter η and the relative neutron-proton asymmetry R_η of the density play a crucial role in the preformation factor of the decay half life.
