| Experiments resulting in the formation of element 113 were reported in February 2004 following experiments carried out between
14 July - 10 August 2003 involving scientists at Dubna (Joint Institute for Nuclear Research at the U400 cyclotron with the
Dubna gas-filled recoil separator, DGFRS) in Russia in a collaboration also involving scientists at the Lawrence Livermore National Laboratory, USA. In these experiments, the primary product were four nuclei of element 115 isotopes. All these four nuclei decayed through
the emission of a-particles to isotopes of element 113. The claim has not yet been ratified, but the results are now published
in a reputable peer-reviewed journal.

| Notes
|
| Currently, the identification of element 113 is yet to be confirmed by IUPAC, but the experiments leading to element 113 are
now published in a prestigious peer reviewed journal. As only about four atoms of element 113 has ever been made (through
decomposition of element 115 nuclei made in nuclear reactions involving fusing calcium nuclei with americium nuclei) isolation of an observable quantity has never been achieved, and may well never be.
