Superheavy Element Research At Dgfrs

This paper presents results of experiments aimed at producing long-lived superheavy elements located near the spherical shell closures with Z >= 114 and N >= 172 in the reactions of neutron-rich isotopes Pu-244, Cm-241 and Cf-241 with Ca-48 projectiles. The decay properties of the synthesized nuclei are consistent with the consecutive alpha-decays originating in the decays of parent nuclides (288,289)114, (292)116 and (294)118 produced in the 3n and 4n-evaporation channels. The present observations can be considered to be experimental evidence of the existence of the "island of stability" of superheavy elements.
