Discovery of Elements 113–118
Review of discovery of isotopes of elements 113–118 produced in the 48Ca-induced reactions with actinide target nuclei is presented. These superheavy nuclei were synthesized at DGFRS; the decay properties of the majority of these nuclei were subsequently reproduced in experiments carried out at SHIP, BGS, TASCA, and GARIS. The increased role of shell effects in the stability of superheavy nuclei with rise of their neutron number is demonstrated by comparison of the experimental data and results of theoretical calculations.
