Synthesis of a new element with atomic number Z = 117.
The measured decay properties show a strong rise of stability for heavier isotopes with Z > or = 111, validating the concept of the long sought island of enhanced stability for superheavy nuclei.
Super-heavy element research.
The radioactive properties of the new nuclei, the isotopes of elements 112-118 as well as of their decay products, give evidence of the significant increase of the stability of the heavy nuclei with rise of their neutron number and approaching magic number N = 184.

Synthesis of the isotopes of elements 118 and 116 in the {sup 249}Cf and {sup 245}Cm+{sup 48}Ca fusion reactions
The decay properties of {sup 290}116 and {sup 291}116, and the dependence of their production cross sections on the excitation energies of the compound nucleus, {sup 293}116, have been measured in
Measurements of cross sections for the fusion-evaporation reactions 244 Pu ( 48 Ca ,xn ) 292-x 114 and 245 Cm ( 48 Ca ,xn ) 293-x 116
We have studied the excitation functions of the reactions $^{244}\mathrm{Pu}$($^{48}\mathrm{Ca}$,$xn$). Maximum cross sections for the evaporation of 3--5 neutrons in the complete-fusion reaction
On the volatility of nihonium (Nh, Z = 113)
Abstract.Gas-phase chromatography studies of nihonium (Nh, $Z=113$Z=113) were carried out at the one-atom-at-a-time level. For the production of nihonium, the heavy-ion-induced nuclear fusion
Synthesis of Superheavy Nuclei in the {sup 48}Ca + {number_sign}{sup 244}Pu Reaction
In bombardment of {sup 244}Pu with {sup 48}Ca , we observed a decay sequence consisting of an implanted heavy atom, three subsequent {alpha} decays, and a spontaneous fission (SF), all correlated in
Investigation of the $^{243}$Am+$^{48}$Ca reaction products previously observed in the experiments on elements 113, 115, and 117
Results from the production and decay properties of element 115 nuclei observed using the reaction ${}^{243}\mathrm{Am}+{}^{48}\mathrm{Ca}$ at various beam energies between November 1, 2010, and
