Synthesis of a new element with atomic number Z = 117.
The discovery of a new chemical element with atomic number Z=117 is reported. The isotopes (293)117 and (294)117 were produced in fusion reactions between (48)Ca and (249)Bk. Decay chains involvingExpand

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 244Pu(48Ca,xn). Maximum cross sections for the evaporation of 3–5 neutrons in the complete-fusion reaction 244Pu+48Ca were measured to beExpand

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 inExpand
