208Pb + 62Ni → 269Ds + 1n
This isotope of darmstadtium decays by alpha decay in 1/20 of a millisecond into an isotope of hassium. In order to determine if the atom of darmstadtium was created, the decay and energies of the daughter isotopes had to be detected. Only four of these daughter particles were detected on November 9, 1994. The IUPAC recognized their discovery in 2001 and the GSI team was allowed to propose a name for their element. They narrowed the choice down to either darmstadtium (Ds) or wixhausium (Wi) after the location of the GSI labs. The IUPAC officially accepted the name darmstadtium in August, 2003.
