History & Etymology
Scientists from the Glenn T. Seaborg Institute and the Chemical Biology and Nuclear Science Division at the Lawrence Livermore National Laboratory, in collaboration with researchers from the Joint Institute for Nuclear Research in Russia (JINR), have discovered the two newest super heavy elements, element 113 and element 115.
In experiments conducted at the JINR U400 cyclotron with the Dubna gas-filled separator between July 14 and Aug. 10, 2003, the team of scientists observed atomic decay patterns, or chains, that confirm the existence of element 115 and element 113. In these decay chains, element 113 is produced via the alpha decay of element 115.
The results have been accepted for publication in the Feb. 1, 2004 issue of Physical Review C.
Kosuke Morita and co-workers at the Cyclotron Center of the RIKEN Discovery Research Institute carried out an experiment on the synthesis of element 113. They published it in October 2004 in the Journal of the Physical Society of Japan. This is the abstract of their article:
The convincing candidate event of the isotope of the 113th element, 278113, and its daughter nuclei, 274111 and 270Mt, were observed, for the first time, in the 209Bi + 70Zn reaction at a beam energy of 349.0 MeV with a total dose of 1.7 × 1019. Alpha decay energies and decay times of the candidates, 278113, 274111, and 270Mt, were (11.68 ± 0.04 MeV, 0.344 ms), (11.15 ± 0.07 MeV, 9.26 ms), and (10.03 ± 0.07 MeV, 7.16 ms), respectively. The production cross section of the isotope was deduced to be 55+150-45 fb (10-39 cm2).
The element has got the preliminary systematic IUPAC name Ununtrium.
The name Nihonium (Nh) was disclosed in 2016 for public review:
For the element with atomic number 113 the discoverers at RIKEN Nishina Center for Accelerator-Based Science (Japan) proposed the name nihonium and the symbol Nh. Nihon (日本) is one of the two ways to say "Japan" in Japanese, and literally mean "the Land of Rising Sun". The name is proposed to make a direct connection to the nation where the element was discovered. Element 113 is the first element to have been discovered in an Asian country. While presenting this proposal, the team headed by Professor Kosuke Morita pays homage to the trailblazing work by Masataka Ogawa done in 1908 surrounding the discovery of element 43. The team also hopes that pride and faith in science will displace the lost trust of those who suffered from the 2011 Fukushima nuclear disaster.
