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

Actinide targets for the synthesis of super-heavy elements
Since 2000, six new super-heavy elements with atomic numbers 113 through 118 have been synthesized in hot fusion reactions of 48Ca beams on actinide targets. These target materials, including 242Pu,Expand

Preparation of actinide targets for the synthesis of the heaviest elements
The heaviest elements are synthesized in heavy-ion induced hot fusion reactions with various actinide targets. Because the actinide material is often available only in very limited amounts, aExpand

Discovery of element 117: Super-heavy elements and the “island of stability”*
ABSTRACT Element 117 (tennessine) joined the periodic table in November 2016. Two tennessine isotopes were synthesized by bombarding 249Bk from Oak Ridge National Laboratory with 48Ca ions at theExpand
