Synthesis of Superheavy Nuclei in 48Ca-Induced Reactions
Abstract
This paper presents results of experiments aimed atproducing long-lived superheavy elements located near the spherical shells at Z≥ 114 and N≥ 172 in the reactions of neutron-rich isotopes 242,244Pu, 243Am, 245,248Cm and 249Cf with 48Ca projectiles. The decay properties of the synthesized nuclei are consistent with the consecutive α-decays originating in the decays of parent nuclides 286,287,288,289114, 287,288115, 290,291,293116 and 294118 produced in the 2n- to 5n-evaporation channels. The present observations can be considered to be experimental evidence of the existence of the ``island of stability'' of superheavy elements.
