In 1974, the Soviets at the Joint Institute for Nuclear Research
announced their discovery of element-106. Three months later, the American group
at the Lawrence Berkeley Laboratory claimed
positive discovery of the same element. The American claim is base on the bombardment
of 249Cf with ions of 18O.
In 1994, the American research group that created element-106 has proposed
that it be named seaborgium, in honour of the discover and Nobel Laureate
Glenn T. Seaborg, codiscover of
plutonium and nine other transuranium
elements. The name was announced at the American Chemical Society meeting by
E. Kenneth Hulet, a retired chemistry from the Lawrence Berkeley Laboratory
and one of the codiscoverers of element-106. Until now, elements have not been
named after living scientists.
